AFAIK, the PowerPC chips run much cooler than P3's.  I'm sure custom
hardware can run even cooler, but I suspect that only in extreme
circumstances would it be worth the extra effort.

Does one extra PIII for an office of, say, 50 people, each of whom has at
least one PC on his/her desk, actually make a significant difference in the
power budget?

An end-to-end IPSec solution that offloads all the work to the end clients
would avoid this issue because one would only be using the PC's already on
people's desktops.
