Try sending your stream to Live365,
which can do a repeater for you. That way, you can up it
to 16kbps mono for better sound and not have the bandwidth
die on you. BUT REMEMBER: It'll give you a server and
a port number. Shout the the port number + 1 (aka if it gives
you port 12222, shout to port 12223).
A "Pure Perl" shouter can be built from my reshouter.
