Might be best to trace him through his companies...
It is a known fact that he owned or was involved heavily with a company called Spheric Audio Laboratories, Inc.,
as evidenced by Steven's ONLY patent specifically with his name on it: US5487113 -
http://www.google.com/patents?id=P2MjAAAAEBAJ&dq=5487113So, we can begin by looking at the records for this company of his.
After a quick search I found this:
http://64.233.167.104/search?q=cache:B5bxYLLmNfsJ:www.secinfo.com/drdbh.93Qe.htm+Spheric+Audio+Labatories&hl=en&ct=clnk&cd=5&gl=us&client=firefox-a"BACKGROUND
The Company conducts business operations primarily through its wholly owned
U.S. subsidiary, PortaCom International, Ltd. ("PIL"). The Company also has
three inactive wholly owned U.S. subsidiaries; PCBX Systems, Inc. ("PCBX"),
Extreme Telecom, Inc. ("Telecom"), Extreme Laboratories, Inc. (formerly known as
Spheric Audio Laboratories, Inc.) ("Laboratories"), all of which ceased
operations in August 1995, and presently have no active business operations.
Since 1994, through its PIL subsidiary, the Company has engaged in initial
stage efforts to evaluate the feasibility of, and attempt to secure, licensing
and joint venture arrangements for the operation of wireless telephone networks,
mobile radio communication systems and other telecommunications technologies. In
September 1995, the Company announced that it intended to focus all of its
future activities on the development of its prospective emerging market cellular
and wireless interests. Although the establishment and operation of wireless
telephone networks and other advanced communications systems will be
investigated by the Company wherever strategic opportunities arise, its
principal efforts are presently focused on certain Asian countries. The
Company's wireless telecommunications operations are in the development stage,
have produced no revenues to date and remain limited in scope.
PCBX developed and was engaged in marketing a personal computer branch
exchange which permitted the operation of a full-featured telephone network
control system from a centrally-located personal computer. Telecom was engaged
in distributing a line of telecommunications products manufactured by Nitsuko
America Corporation. Laboratories developed and was engaged in marketing a line
of audio speakers, as well as a proprietary audio recording and playback
technology known as "SphericSound." PCBX, Telecom and Laboratories ceased
operations in August 1995 and presently have no business operations.
Since the commencement of operations, the Company's revenues have been
principally derived from the sale of its PCBX systems and to a substantially
lesser degree from sales of Telecom and Laboratories products. Due to
significant ongoing losses and the Company's inability to successfully develop
and carry out marketing and sales strategies, the operations of PCBX, Telecom
and Laboratories were closed in August 1995. The Company also attempted to
secure licensing arrangements or other means of commercial exploitation of its
SphericSound technologies; however, to date, only limited sales revenues were
realized from these efforts.
Funding of the Company's operations since inception has been provided by:
(i) revenues from the sale of PCBX systems; (ii) proceeds from the sale of
securities undertaken in a series of private placement transactions; and (iii)
completion of an initial public offering on the Vancouver Stock Exchange during
October 1992. "
So, Spheric Audio Laboratories aka Extreme Laboratories effectively ceased business in August 1995.
Extreme Labs last known address:

Stemming from the patent, and his association with Spheric Labs, which changes names to Extreme Labs...
See this page:
http://64.233.167.104/search?q=cache:AAR90w2VUOAJ:www.mishkan.com/sca.html+%22David+Doleshal%22&hl=en&ct=clnk&cd=16&gl=us&client=firefox-aIt is a conference in CA with this listing:
"The Legend of Jesus in Pre-Agricultural Shamanic Mythology David Doleshal, Extreme Labs"
This was a talk given by David of Extreme Labs, at Berkeley...Note the date of the conference, 1995.
A bit more searching and we find:
http://64.233.167.104/search?q=cache:pT21OoGsqZgJ:www.worldpolyamoryassociation.org/Faculty/faculty_ABCD.html+David+Doleshal+berkley&hl=en&ct=clnk&cd=1&gl=us&client=firefox-aWhich states:
" David Doleshal. Ph.D. Dave has a Doctorate in psychology from the University of California, Irvine. He has been studying innovative techniques for the treatment of emotional issues for more than 20 years - most especially methods related to jealousy management and the healing of emotional traumas. Dave is the facilitator of the Polyamory Support Group in Berkeley, California, and is one of the co-founders of the World Polyamory Association. He is also the director of Saturnia Regna, - a Political Action Committee specifically organized for the promotion of the cause of polyamory. He lives in Berkeley, California.
"
There is that link to Berkeley again...
Maybe it is him, maybe it isn't...But, if you really want to find Steven Mark, you might have to talk to David...
I am listing all this info, one, because it is public knowledge, and two, because many are actively trying to find SM and I am just providing you paths to do so.
