There's an even easier solution, IMHO.  I wanted to use the horsepower of a
couple of pretty powerful workstations for commercial flagging, so I made them
slave backends with the master backend mounted via NFS and with no tuners, set
their job search interval at a fraction of the master backend, and set their
job limit at 2 and the master backend's job limit at 1 (I also used 0 for a
while to disable it completely).

The upshot of this is that these slave backends end up doing all the
commercial flagging instead of the master backend.

To also partially answer your question, my athlonxp 2400+ workstation seems to
be able to easily do realtime commercial flagging on at least one sdtv show
(from a pvr250 at high capture res) at once.  My second input is an hdtv card
and the demands of flagging hdtv are much higher, of course, so I can't really
tell you if it could do two sdtv shows at once.
