Perhaps you can answer something that's been bugging me for some time. 
How does this actually work?  I mean, what gets sent over the wire when 
you redirect a serial port?

It's always bugged me that there's not much information about how this 
is done, and it seems to use a bit too much magic for my liking.  I 
mean, is it TCP?  Can you restrict access to it with a firewall?  How 
does it share the network card with the host OS, in the cases where you 
use the one NIC for both?
