In such a system, your biggest bottleneck will likely be bandwidth to the hard
disk(s). If you've got 4 folks watching HDTV streams, that's a TON of data
the gets written and read constantly. Some sort of RAID setup, or 1 or more
slave backends may be necessary.
Thy only reason to have a beefy CPU for your setup is transcoding to mpeg4 to
reduce file size.
