Actually you are already all set.  The VGA/Mac adapter does the shorting
for you.  Just unplug the monitor and leave the adapter in place.

This is really a good *general* solution because the adapters usually allow
you to set what resolution, etc. you want to use.  If you have a Mac
monitor and two Mac's then buy an adapter for the other computer, set it to
the kind of Mac monitor you really have, and use it to fool whichever
computer doesn't have the monitor on it.  Then you can trade whenever you
want.
