Just saw this post about xGL development closing up. My thought from that post was Novell thinks in house development is better or they don't want to collaborate with others (who are interested in xgl, ie users/developers from redhat, debian, gentoo, ubuntu, ...).
So I thought I'd put my box back up here and populate it with the xgl instance as well as other examples. I've put some examples of projects that appear to be going in the opposite direction. For those that are moving to open source, there appears to be commercial activity building on top of them (the curvy line). (Though I'm not sure that the curvy line actually goes to the right, it might go back to the left depending on a few factors). I'd love to hear comments or feedback...
