Sounds like you want some sort of bi-directional version of 'tee',
so you could tee the device to a file and leave the other end open to connect 
with the client (screen sounds like it does something functionally similar, 
although with a different mechanism).  I can't think off-hand of a way to do 
this.  I'm sure it's been done before though.  What about regular tty 
loggers?  I know I've seen tools that let an admin log all tty traffic, tools 
which are external to the shell (but since I've never had the need, I didn't 
pay close attention).
