Yes, the library to talk to the device is opensource, the hardware, not
so much. :)

Since a lot of video cards dont' support CEC at all (not even
connected), don't have hdmi, but work perfectly fine with dvi->hdmi
adapters, CEC can be implemented in many other ways (think media centers)
One such exammple is using USB/Arduino
http://code.google.com/p/cec-arduino/wiki/ElectricalInterface
Having an AVR with v-usb code and cec code doesn't look all that hard
nor impossible, so one could simply have a USB plug on one end, and an
HDMI plug on the other end, utilizing only the CEC pins.
This would make it more something like LIRC if anything.
There already exists a device like this (USB CEC adapter with hdmi
in/out) with open source userspace driver, developed for the XBMC Media
Center (apparently MythTV is also supported):
