It may help, if this is what other people do in a similar situation.
Greg mentioned testing it in the wild, but I'm not sure that's practical 
for us.
I know Bram Cohen did it for BitTorrent, but our dynamics are slightly 
different.
We have a p2p streaming app and it's going to be difficult to find 
something that enough
people are going to want to listen to or watch that will create a 
network of a million users or more,
which is the kind of number that we want to test against.
If it was that easy to do, I guess we'd all be in the content delivery 
business ;-)

Cheers,
Frank.
