Company computer utilization?

Pardon my ignorance here, BUT....

What about some type of "grid" computing similar to SETI? It would only need
a client installed that could be configured to run when the PC had been idle
for "X" minutes/hours and would SURELY be simpler to implement than
re-loading "100's of P4 and P4 Xeon boxes". The later is surely to irk
someone with stroke to get the whole project kinked.

True, there must be etherboot drivers for the network cards you are using.

GRUB does not 'support' the netboot/etherboot system, they 'incorporate'
the etherboot drivers to create their own network booting mechanism.

The compelling reason is that you don't have to burn a bunch of ROMs and
pop open boxes to put the ROMS in the video cards.
