This is an interesting idea. It's not a replacement for periodic probing, because there's no guarantee the crashed server will come back in a timely manner, if at all. But, crash reporting could speed up the resync process. I think this could already be done today by keeping a list of presences you have sent out, and upon restart just connect to all of the servers and send unavailable presences. There's probably major optimization potential here with XEP-198. -Justin
