this part of the lac streamteam must confess it doesn't have the
faintest... which may partly be attributed to sushi deprival syndrome.

even though i hosted stefan's nat-piercing script for one of marije's
projects, i never bothered to find out how it works... i guess it's a
reflector that actually bounces the data back and forth.

i'm very sure that's not what you want for a netjack connection if you
care for latency. plus you would burn huge amounts of bandwidth for
basically nothing.

the way i see it, if you want to netjack between two natted hosts,
there's no easy way around port forwardings on both ends. which is fine
imho, since we are not competing with skype here, are we?

for the simple case (both end points have real ip addresses), some
simple directory script (such as the icecast streamer list) might
suffice, but the cool thing about the jabber idea is you can ssl it and
maybe also use it to agree on a login procedure without having to post
your ip (and hence, your open netjack port) for all the world to see.

(btw, torben, great to hear from you again! do get in touch if you ever
need a crashpad in essen.)

best,
