This is one of the things the pollForRequests does: identify incoming, 
unsolicited messages and do sensible things with them.  Naturally, the 
contents of the message will have to provide some info about what 
"sensible" implies, because pollForRequests will have to handle not only 
receiving pushed tags, but also various parts of micro-migration. 
Details will of course be implementation dependent, but pollForRequests 
is arguably the most complex function in the interface to implement.
