I don't know what the details are, but both Zha and Zero claim that no 
existing chat system quite fits the use cases for SL-style chat. I'm 
pushing to implement regular SL chat in the OGP for now with the AD 
acting as a relay, so 1) we can have a sense of community in the OGP and 
2) we can see what actually happens to the current system in an 
intergrid/AD world.
