OK. While I didn't wind up going with Darwin Streaming Server, I did get a couple of alternatives together and downloaded them and installed them on the linux box. They are simply VLC and Mplayer. They're both great media players (at least VLC is - I've not tried Mplayer yet), but I've not used them in setting up a VoD server yet. As soon as I figure that out, I think we're off to the races. Still, what has been accomplished today have been great steps forward.
