Well... The obvious way is to run the program under X, and export the
DISPLAY to the machine local to you. (On the machine local to you, you'd
need to type xhost + <hostname of remote machine>

Start any X program then, and it'll appear on your machine rather than the
one running the program. (This includes Xterms, so you can still run console
apps)

If you mean hijacking the output of a running program. Only if your program
produces logs, I'd think. Don't think you can re-assign a display to a
running one unless...

You could run "screen". Then you can detach it from any terminal and
re-attach it to any other terminal. (via ssh or telnet)
