Interesting proposal. Let me some questions:


1)
- Alice has two active resources (alice-1and alice-2).
- alice-1 uploads a new vCard.
How is alice-2 notified about that change if there is no possibility
of subscription to the vcard?

2)
IMHO avatar should be part of the vCard (as vCard already includes
photo and so):
- Alice is subscribed to Bob's presence (just presence).
- Alice retrieves the vCard (including avatar) of Bob. But there is no
subscription as you said.
- Bob uploads a new version of his vCard with a new photo.
How is Alice being notified about the change to display the new avatar?

3)
Where is the limit to say "this info requires subscription but this one not"?
