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.
