I recently saw a concert here where they plaied with musicians in 
france over the net. They made a big thing out of it and the public 
did not quite realize how the delay screwed it up mostly.
It worked reasonably for a shaman voice meeting, where time was not 
so important. Marcus Susano and a brilliant italian panderist found a 
way to play fast enough and pingpong the base beat that turned out 
interesting.
I sounded best when the french guys had a electronic groove going, so 
they did not try to match the beats coming from here. But in france 
this same part must have sounded off!
I thought of exactly the solution you already programmed, it seems: 
if the delay is extended to exactly the length of a loop, we do not 
answer correctly to the immediate playing but at least build on the 
loop together.
But how do you detect the correct delay correction since the delay 
over the net is not constant?
Reminds me of the net time syncronization: How can they send you the 
exact hour if they dont know how long the message takes?

So maybe the first net-concert that will groove well will be a 
loopers meeting? :-)
