If AAL5 cells can't be interleaved because there's no way of unscrambling 
them after the fact,

If there would tend to be few senders and many more receivers in a mpt-pt 
connection, and

If one wants to establish one VC for the mpt-pt connection, then

I wonder about a bastardized use of VPIs? How about each sender uses the 
same VCI but different VPIs? This would allow interleaving of AAL5 cells 
at all merge points while still keeping them identifiable. And scaling 
might not be a real problem.

This strange use of VPIs could become a problem when the intended use of
VPs is implemented, but then again ATM switches could manage both uses of
VPs separately, no? Couldn't switches dynamically keep track of which
VPIs were to be terminated at own switch for mpt-pt connections, and
which VPIs were just for cells in transit?

Somehow, the meticulous buffering of n packets' worth of cells along the 
way is sure to incite the ire of the ATM god.
