If the remote server ever goes out of synch with your own server's
presence subcription, you'll have a big (undetectable) problem this way.
This also demonstrates the problem that it's no longer your own server but
someone else's who is keeping your presence subscriptions. Eg let's say
you're on server X, and have a contact on server Y. If I have access for 5
minutes server Y's database I could create a false subscription (on server
Y) to your presence. Previously this wouldn't do me any good, but now I
can detect your presence without you knowing it, and without any more
"proof" than a database entry (no need to run a background program on the
hacked server or anything like that).
In the least is should be included in the security considerations.
