 Actually I think serial port won't be sufficient actually. I am looking at it 
from purely manageability perspective, but even then, serial ports does not 
allow multiple simultaneious streams. I think in tcp/ip, the server gets a 
connection at a particular master port, say 80, and then it creates a slave 
socket at another port and spawns a child, and child actually carries out the 
communication through this slave port. I am not really an expert in networking, 
and that's my generic idea of how networking happens. Will such a system be 
possible with serial ports. I don't think so. I think I will I have to come up 
with some protocol to make multiple streams through serial port possible. 
Anyway, a generalized tcp-like communication stream independent of the 
networking stack looks like a good idea to me.

 Or maybe you can build a networking stack kind of thing on top of the serial 
port. I am very new to Xen, and I will have to first get a proper system 
running on it test it further.

 Thanks for your comments.
