According to the registry in the Finder Suite of AppleEvents is an event called
aeOpenSelection which is used to tell the Finder to open "any kind of object
which the Finder can open."  Also the Scenarios portion of the Finder Suite
introduction says, "Users can launch an application on a remote machine by
sending an Open Selection event to the remote Finder."

Does this work?  If so it sounds like HyperTalk's "open" should use this means
to launch applications if the target is a remote machine.  (Applications like
HyperCard shouldn't be worried about the security implications of doing this;
AppleEvents itself should and does implement security.)
