Streaming Question

[Tim Stein]

Hi there:
New guy here, and I have a question about my website: www.wrestletalkradio.com. We stream a live audio show Sunday nights on our site and archive them for later listening. The shows I encode into .rm files, with a .ram file that points to the file which enables streaming directly off my server instead of having to d/l the show to listen to it.
My question is this: We interview "celebrities" of the wrestling world and I cut those and post them separately. Is there a way to leave it as an mp3 on the server for quality, but stream it instead of having to d/l and open a large (for dial-up) file? I am thinking that I'd just write the .ram file to point to the actual file itself, but I was hoping to discover a better way, if there is one.
Thanks in advance!!
