Subject: * This update enables grid wide presence updates. * You'll need to
 start-up the MessageingServer and set it up.   It sets up like any of the
 other grid servers. * All user presence data is kept in memory for speed,
 while the agent is online.   That means if you shutdown the messaging server
 or the messaging server crashes, it forgets who's online/offline. *
 Occasionally the region-cache will get stale if regions move around a lot. if
 it gets stale, run clear-cache on the messaging server console to clear the
 region cache.
