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.
