Don, since you asked your question you piqued my interest in streaming servers and I am aking a look at Darwin Streaming Server, the open source version of Qucktime Streaming Server.
I have it sort of running on FreeBSD (there is a port) but I am having difficulty. However I am yet to read this very good looking help doc: http://helpqt.apple.com/dssWebAdminHelpR4/dssWebAdmin.help/DSSHelp.htm It seems to have some good info at first glance, it may help you get acquainted with the area. Nick.
