It's really great to see this. One of linux's greatest weaknesses is the amount of duplication that happens. Sometimes it's necessary but a lot of the time the community would be better served by everybody working together instead of against each other. This is one of those times and I applaud the beryl and compiz devs for realizing that and having the good sense to swallow a little bit of their pride on both sides. I'm looking forward to the great things that will come out of this.
