Temporary Lists of Recipients - proposal for XEP33

When I started my Google Summer of Code project three months ago, Tobias Markmann pointed me to his Temporary Lists of Recipients proposal.

The purpose is to reduce even more the bandwidth consumption by sharing a common list of JIDs between the two entities which maintain a XEP33 communication.

The idea seems worth to be considered... once the current XEP33 is already implemented and deployed in the XMPP world. So I bookmark this proposal for future reference, and let's see what happens.
