Note that TFM says that an *interactive* command (e.g. vi and most games)
should *not* be run using remsh, by rather by rlogin to the machine.

I don't recall why (probably because the TAM version does something
strange as you describe), but I wrote a small routine which checks the
controlling tty to determine if a process is running on the console. It's
near the end of kfeature 1.1 if you want to take a look at it.
