Yeah, I've been reading up on it since my first post.  As you said, it's not really what UPNP was designed to do.  Any suggestions for getting my media streamed off the plug to anywhere?  I looked at mpd but it seems like that requires a sound card, which I don't think exists on the sheeva.  In any case, just having the media streamed around the house is still pretty cool!

Thanks a lot for the information.  Mine is up and running on my internal network now.  Do you have any links or tips for getting this served up over the internet?  I have a smart phone with a data plan, and something like Pocket Tunes Deluxe connecting to my sheeva is my goal.

Could you post your .coherence file and any extra options you start coherence with?

Since no one has mentioned it yet, I'll say that I'm using rtorrent + screen on my sheeva.  Sorry that I don't have any CPU utilization benchmarks, but it is probably the lightest client out there, as well as being very configurable.   I've always used it in the past precisely because it was an all command line method, but I also should add that I'm very impressed with rtGui.  The ability to control it, including adding new torrents and deleting finished ones, from any web browser anywhere is pretty handy.

I have been using screen and rtorrent for a while now, but I just set up rtGUI a few minutes ago.  It is pretty slick.

Is this possible?  I've got mpd up and running and serving out mp3s, but I get no sound on any of the two client machines I've tried.  I figure this may be due to a hardware limitation from the plug, but does anyone know if this is possible to achieve?
