I'd heard about Octoshape a few years ago, and it's an interesting 
application of a technology that I never thought would have any legs (AMT). 
But I'm often wrong about predicting the adoption of new technologies - I 
proselytized native multicast for many years ;) I didn't think that it 
depended in any way on native multicast, though. Are you saying that these 
networks are extending native multicast out to the edge equipment, or that 
they're using it internally and letting Octoshape handle the last part of the 
path? And are they using multicast intra- or inter-domain? I've heard of 
streaming providers using it within their own networks, but not allowing it 
to leave their boundaries.

PS - also, does Octoshape have an IPv6 story? I found something on your 
website, but it was from June 2006. . .
