On the general issues of switch boxes -- how are folks
switching. 

Since the serial protocol of mice and keyboards does not support
multiple contexts all a magic box can really do is multiplex the
inputs.    If you switch in the middle of a character or in the 
middle of a multi-character control sequence there is no way that
a magic box (without complex logic) can keep all things in order.
Sort of like mixing top and bottom posting does here ;-)

I have an old Belkin switch box and have no trouble.  I do however
only use the buttons on the box to switch and not the function escape
sequences.  There are also issues where a keyboard can be programmed
to send special sequences it could expect to retain these so machine A
with special sequences borks when these sequences are sent to machine
B or some combination of the above.

So the question is how do people use their switch.

It makes sense that some defensive programming could be included
in the byte stream handler in X that could tidy things up when
there is a protocol error.

I also use remote X display via ssh a lot ;-)
