Well, Im really not against it. However Im not sure if everybody really
understand .ffm features and what it was designed for.

.nut won't pass any options to "ffmpeg" feeder, and I don't think
cycling through a .nut file would be as easier as with .ffm (with
constant packet size).

FFserver supports time backbuffer.

Now of course this can be redesigned, and will probably be better,
though this would mean a major rework.

Yes, though Im working on this extending it to transport pts and dts.

In some way, however I added AVOption transport feature (as a string)
and it works quite well.
