It depends on the resolution and bitrate you're using. I do 480p at 1,300 kbits on an i7 3770 and the processor barely notices. On tablet screens DVD res and that bitrate gives a great picture. I haven't tried 3 clients but that shouldn't be much trouble.

No, but it does require h.264. If your material is already in a res/rate that your device supports then...

Apple has an open source utility that will segment existing videos but that's moving outside of what myth does. You'd have to develop your own http server that takes myth program IDs, finds the file, does all the segmenting, and serves up the resulting files. It's doable but I doubt it's worth the trouble.

On a local LAN with tons of bandwidth and material that's already in the right format for your device I'd just dump it directly to your player without transcoding.
