i've been wondering the same thing for a long time now. i'm on gentoo, which i've been very happy with for the most part. unfortunately, i can't get php to emerge properly (because a certain dep doesn't emerge properly) so i can't emerge subversion, so i can't follow the instructions at
http://kopete.kde.org/svnaccess.php . seems like even if i could follow them, i still wouldn't be able to broadcast from my webcam...
it's all very frustrating. i bought a new linux-compatible webcam just so i could use it with kopete and talk to my friend who lives in a different state. i've tried other chat programs that are supposed to support webcams but they all either don't install properly, or they just suck.
i hope someone fixes this soon. i would be overwhelmed with joy.
