I just read this great blog entry about how metacity is finally startign to get onto the composite bandwagon. Anywho you can download the the metacity svn and configure it for composite. So what does this mean? omposite for a lower price on cpu power. Basicly you dont need to run Compiz Fusion or xcompmgr to use awn or screenlets or any other composite needy program. While xcompmgr is also on the lite end compared to compiz fusion, I believe development has been stopped on it. So far I have tried it out and it has been pretty nice and fast, and also they seemed to have made the minimization a little more snazzier but not the maximization... anywho if you want to check it out instructions can be found on this blog post.
