But if all the products (Finder/Multifinder/Hypercard/MPW) are produced by
the same company, wouldn't it make sense for the various software engineers
to let each other in on their secrets?  Since Hypercard's ability to launch
other applications is a very "system-software-ish" sort of thing, I still
think it would have been nice to have implemented the Multifinder kludge.
