Another way to pull off the trick would be to use some remote desktop software like VNC (or something similar) to bring another machine's desktop onto the primary display. Aside: Last time I tried VNC, it was a bit dodgey when working between dissimilar CPU architectures. E.g., Wintel, Linux, FreeBSD on x86 machines worked well together, but going to Sparc Solaris or PPC OS X was kind of jerky, with irregular and sometimes long delays refreshing the remote'd display. Maybe it's been fixed. Romain Kang Disclaimer: I speak for myself alone, romain at kzsu.stanford.edu except when indicated otherwise.
