As we're be start working at the new library in order to support
complex cameras, and I don't want to prevent you keeping doing your
work, IMHO the best way to keep doing it would be to create two
libv4l2 forks:

- one to be used by you - meant to support N900 camera;
- another one to be used by Google/Intel people that will
be working at the Complex camera.

This way, we can proceed with the development without causing
instability to v4l-utils. Once we have the projects done at the
separate repositories, we can work on merging them back upstream.

So, please send me, in priv, a .ssh key for me to add you an
account at I'll send you instructions about how to
use the new account.
