I may be wrong on this, but I think that RSVP only takes a "single pass"; 
if there are multiple paths, and the routing policy says "Take Path A", but 
Path A doesn't have sufficient RSVP bandwidth, the stream _doesn't_ take 
Path B instead, even if path B has enough.

I hope that someone can prove me wrong, or I'm mis-reading the RSVP design 
guide.
