I believe part of the problem lies in the fact that many applications are
not licensed to be placed on file servers and multi-launched.  Therefore, if 
10 people want to run their Mac??? software package, they should actually
have 10 copies of Mac??? on their file server.

Most applications that are well behaved (e.g. follow TechNotes 115/116)
by not writing to themselves, numbering temporary files can be made
sharable by setting a bit using ResEdit.  Unfortunately, many applications
are NOT well behaved, e.g. they hard code their temp file names, store
configuration information in their resource/data fork, do not check for
result codes from File Manager and Resource Manager calls, etc etc etc.

Writing an AppleShare compatible application requires some thought.  It is
not as easy as writing a MultiFinder compatible application because you
need to check all File and Resource Manager calls.
