Well, the problem is that once we define a binding for displays, we will 
have to keep support for this binding even if we decide to change 
something.

But as I discussed with Laurent and Alexandre at LinuxCon Japan, we should 
be able to reuse V4L2 bindings for our purposes, so someone just needs to 
code a proof of concept implementation that doesn't necessarily provide 
full functionality yet, but allows to make something work. Probably based 
on already posted RFC versions of CDF.

CCed Laurent and Alexandre, as they might be able to shed even more light 
on this.

Best regards,
Tomasz
