That is a reasonable compromise. It is certainly easy enough to keep a 
set of the "last known" Yahoo contacts that have been placed on the 
user's roster. I'll have to test to see if there is any down side. I 
also like the unsubscribing of jabber contacts that are no longer on 
the legacy roster. Right now, they are left on the jabber roster ....
