I have some machines with gigabit, and a gigabit switch, but right now
my master backend only has 100MBit.  I can record two HD streams from an
HDHomerun, and 2 SD streams from PVRx50 cards, plus watch at least one
stream on a remote FE without problems.  I haven't ever clocked the
exact network usage under those circumstances, but it doesn't seem to be
saturated.

That would make sense, considering that the SD recordings are set to
roughly DVD quality, or max 8 Mbits/sec, HD are about 20-25 Mbits/sec,
so the above traffic would total 25+25+8+8+8, or 74 Mbits/sec in the
worst case.  If your network is busy with large file transfers between
PCs, it could be a problems, but the overhead from web browsing or
similar activities would still have room.
