right.  for interest, "real" servers also tend to have IPMI, 
which is a network-able standard that often includes a small
coprocessor, and also gives access via SMBus sensors.  among the 
most valuable features of IPMI-type remote-management interfaces
is the ability to cold/warm reset, power on/off, and often have 
some access the bios/console.

I'm not sure why, but SNMP doesn't seem to go along with IPMI-type
remote management widgets.
