Well, if you are using a system with PTY's, you can write a program
that opens both devices, fork another process (to actually read
and disturb the input :-), and dup the file descriptors comming off
of the PTY to whatever the new process will expect, and then
exec the new program.

Then, in your parent process (the one that originally opened the
PTY), you could sit in a loop, getting input from the mouse
and keyboard and passing the data along the apropriate PTY.
