I have a review copy of a Tech Note on Multifinder.  (Since it hasn't been
oficially released, I won't go into specific details, but just give you the
basic ideas.)

The question is why do you need to know whether you are running under
Multifinder?  Usually, you just want to know if one of the Multifinder
features is available (eg, WaitNextEvent, temporary memory allocation, etc.)

In this case, you just see if the appropriate trap is implemented or not.

Multifinder does not use the same Switcher globals, since its does not
provide the same programmatic interface.  (If it did use the same globals,
applications that could work directly with Switcher might get confused.)  In
fact, part of the test to see if Multifinder is installed is to check the
Switcher globals to make sure Switcher is not running.

Tech Note #126 describes how to do sublaunching, by passing extra
parameters to the Launch trap.  I believe that if you follow this Tech
Note, then Multifinder will launch the application in its own partition
without terminating the parent.
