The solution I have used is to use pseudo-terminals and a
session-logging program.  In other words, you have the user with the
problem log his terminal session to your terminal.  No kernel mods
necessary, and I beleive that there are terminal session logging
programs available for 4.2 BSD (the one I use is for another OS
entirely.)  You can't take over the user's terminal session with this
scheme, but it is available "off the shelf" so to speak, and serves most
of the needs.
