The license is very restrictive, but limited to only the output issues.
However, it appears to me that the OGC could easily comply with it as
long as all that is needed is to provide an DHCP encrypted HDMI output.
You have no idea, how restricitve the HDCP license is.
It denies you the right to give out documentation of any
system that can encrypt/decrypt HDCP streams to anyone
who does not have a HDCP licnese. It even requires that
no HDCP encryption/decryption chip is sold to any entity
who does not have a license.
I personally don't see any way how we could comply with
these restrictions while still be true to our original
goal of having a completely documented graphics card.
If the encryption is done inside of a commercial chip, then the only
issue is how to prevent sending out an unencrypted signal when this is
not allowed.
There are probably several specific ways to accomplish this but they
would probably all require a OTP MicroController potted on the board and
the routing of certain PCB traces to the center layers of the PCB.
We could easily make something that was more secure than current PC
hardware running under Windows Vista.
