Thanks for the replies.....not sure it'd be worth changing over to Comcast at this point, because their upload speed is basically the same as the DSL connection. And yeah, I could either use dyndns or the Streamweb service to get around the dynamic IP...still debating...this would coincide with a move, so I have time.
I thought the hostname was having trouble resolving from work, but another guy clicked on it and up it came, so I guess the configuration is valid for a static IP.

Download and install Winamp. Nice thin and free player. There are many other free players that are a lot thinner than WMP.
Go
here and download/install Open Playlist in WMP. Associates itself with .pls extensions and will open Media Player and play the stream automagically. Supports AAC streams as well.
