1.  It's called a console server, or a terminal server, depending on  
whether it performs the multiplexing or demultiplexing function.   
These have been around for twenty years, and they don't require  
device drivers.
2.  To reiterate:  a) this is a solved problem, b) with a strictly  
user-space solution.
3.  Greg, kindly take me off this list.  Deregister me, deactivate my  
account, whatever.
