OK, here's my strategy...
First off, I've settled on two formats for various reasons. Windows Media (streaming) is one, because the server software is on my server anyway, it's available for PC and Mac, it looks damn good, and I can encode one file that adjusts to your connection speed.
The other format is QuickTime, which can quasi-stream (HTTP) without server software, looks fabulous at that 12 MB threshold, and it can be downloaded for keeps.
