Hi Renato,

It seems inevitable that automatically maintaining any bidirectionality
would fail against (e.g.) me adding you to a group I created in my
addressbook which references your vcard from your addressbook home on
that same server, for the permission reasons Simon mentioned.

Or (even more impossibly) maintaining backlinks to my offline
addressbook collection which refers to your online vcard.

However there might be reasons to indicate group membership in the
reverse direction (separately to any capability of automatically
maintaining such links), but it is not clear to me that this would offer
anything more than can be achieved by simply adding a category to the
vcard.

Regards,
					Andrew.
