Dave, again please remove my identifying information.  Thanks.

Put up or shut up?  Sounds fair.  Read
http://www.dtcp.com/data/wp_spec.pdf , paying particular attention to
discussion of device certs and revocation.  A "device cert" is a
certificate, signed by a central authority, stating that some
bitstring represents a key securely in the hardware of that device.

Or look at the statements from http://java.sys-con.com/read/46424.htm
, that each device has its own unique cert and key.

Or look at Digital 5, a member of some of the DTCP groups, referring
to it as DRM at http://www.digital5.com/news/press_122904.asp

Or look at the discussion of doing this outside the IEEE standards
process at http://java.sys-con.com/read/46424.htm .  That site's
particularly interesting in its discussion of the controls they intend
to impose on even *unencumbered* data that enters your home.  It also
discusses the fact taht each device has its own certificate and key.
Who's saying all this juicy stuff?  A staff engineer with Intel, Steve
Bard.

And Intel's own statement on this said the 945 Express Chipset does
support DTCP-IP; they just called it Content Protection instead of
DRM.  So I think it's pretty clear that DTCP is DRM, and that it is
in at least some Intel Chipsets (e.g. the 915 and 830).    Given the
HD-video capability in the 945G Express, it seems quite unlikely that
there's no DTCP support in there.
