This would be great, and it is what I was advocating also, except that it
appears to violate the protocol:
'If the user is not in the contact's roster with a subscription state of
"From", "From + Pending Out", or "Both" (as defined under Subscription
States), the contact's server MUST return a presence stanza of type "error"
in response to the presence probe...'
So much for that idea. :(
