We've done rather large point-to-multipoint video, thru several switches,
and to a hundred video end points.  PVC (and/or 'soft' PVC)s are used.  The
network was not oversubscribed, so everything was done using default UBR,
although CBR would be appropriate.  With modern management tools, setting up
mesh and point-to-multipoint PVC's is not what it used to be...it's quite
simple and easy.

We used no MARS or MCS, just VBricks and ATM switches.  Hope this helps.
