It occured to me that this issue actually relates to a recurring
problem we have in XMPP. When an account is removed from a server we
remove subscriptions to their contacts also. Unfortunately there is no
standard way to know what services an account may have also been
associated with, and so no way to notify them of the accounts
deletion.

I don't have any other input for the actual protocol yet, I'll leave
that to someone else for now :)
