Xenocara is where all "new" work is done, this means the further exploration of EXA, Support for MPX, Improved Hot Plugging.. a overhaul of how Xorg handles PCI devices, (
Apparently in a cleaner fashion..)..
The licence tidbit that happened in the XFree86 camp seriously damaged their reputation, many of the old developers have moved over to the new project.
Xorg is now the
de facto reference implementation, it's now default in Linux distributions, FreeBSD, and now OpenBSD via the Xenocara tree. (
The developers forked Xorg locally and added some local changes, they still sync with the main tree quite often though.. 
).
Slightly related but the person essentially spear heading the support of DRM/DRI on OpenBSD had his laptop stolen, perhaps someone here should land a hand?
