I think I once created a streaming audio thingie on my private website, 
accessible by SSL and connected to that -over SSL- with stunnel on the 
client-side.  It worked like a charm.  Can't remember what it was though.

If you look at this page 
http://www.linuxforum.com/linux_tutorials/77/1.php it has some shoutcast 
ipchains rules:


# Allow inbound Shoutcast
ipchains -A input -i eth0 -p TCP -s 0/0 -d 0/0 8000 -j ACCEPT
ipchains -A input -i eth0 -p TCP -s 0/0 -d 0/0 8010 -j ACCEPT
ipchains -A input -i eth0 -p TCP -s 0/0 -d 0/0 8020 -j ACCEPT
ipchains -A input -i eth0 -p TCP -s 0/0 -d 0/0 8030 -j ACCEPT

#Speed up output of Shoutcast w/TOS arguments
ipchains -A output -p tcp -d 0.0.0.0/0 8000 -t 0x01 0x08
ipchains -A output -p tcp -d 0.0.0.0/0 8010 -t 0x01 0x08
ipchains -A output -p tcp -d 0.0.0.0/0 8020 -t 0x01 0x08
ipchains -A output -p tcp -d 0.0.0.0/0 8030 -t 0x01 0x08

Which would lead one to believe that shoutcast is really TCP.

The shoutcast docs speak about a port + 1.

Why don't you just connect to it cleartext, check with tcpdump or ethereal 
what traffic goes over the wire and if it's tcp to/fro one port you can 
tunnel it with stunnel :).
