Indeed, I only know one Compositing Manager, namely xcompmgr. Kwin, Compiz
and others are Compositing Window Managers, which is not at all the same
thing.

Surely it would be interesting to port a Compositing Window Manager to
XCB, however I'm personally more interested in a Compositing Manager as I
think something generic, which could run along any EWMH-compliant window
manager such as Awesome (even if there will certainly be a certain amount
of work to make it compliant), would be much more interesting.

Anyway, I'm about to leave for the WE, so I will send my announcement
afterwards ;).

Cheers,
Arnaud
