It is just the built-in xtalk system for sending and receiving 
appleEvents between scriptable apps. Like I mentioned in another post, 
you use "send" to send an appleEvent to any scriptable app. If the app 
is a Rev standalone, an appleEvent handler is required in order for it 
to receive the instruction and act on it. If the receiver wants to 
return a response to the sending app, it uses the "reply" command to do so.

The default behavior for "send" is to wait for a reply until the timeout 
period is over (I forget what that is, but if I remember right, it is 
pretty long; I think it used to be 2 minutes on OS 9.) If the sender 
doesn't want to wait, it can use "without waiting" to just fire off an 
appleEvent and continue on its way.
