just a clarification - i meant this question to be framed in terms of a
control channel for access in place of a monitor/keyboard switch NOT
as a replacement for networking. many clusters are installed w/o vga cards
and keyboards b/c for the most part they are not needed, but if you want
to experiment with interesting/creative networking (say channel bonding on
a beowulf or different arp scenarious with ha clusters) this could be
really useful.

thanks :>
