That sounds very interesting. I'm not experienced in writing these drivers.
(note to lurkers and alike: much much specialized knowledge needed for that,
I'm actually reading feedback control systems literature from uni ATM trying
to understand PLLs better...)
But I do juggle around the commonly available kernel drivers for supported
analog cards (and a class of webcams) for use with (or without) kbtv. So at
the very least I may be useful to help tie some knots together. Of course
with these things it's really imperative that I actually have the HW (I have
an eyeTV hybrid stick here on my desk looking at me).
People often don't understand that: you really must have the HW except for
some general/lucky cases.

Whether a unification on kernel(-mod) level like v4l is doable or desirable or
not is up to debate, but I think not, IMHO v4l is better avoided on freebsd
even if some compat thingies exist, if only for performance and driver
simplicity. Just provide sane ioctls that can do the common things. I think
you and I are pretty much on the same page there.
I browsed the cx88 code on your site a little while ago, but only glanced
through it. Looked interesting, but I got the impression that to try and
build something, one would first need to build (port) other existing linux
kernel mods.
Anyway, I very much welcome such an initiative and will likely participate one
way or the other. Be prepared for stupid questions!
