I agree, AppleEvents are easier and faster than AppleScript.
However, in my particular case, it was UDP I used.
-1- I need both Win and Mac
-2- the Rev 'do script' was broken until 2.7  When I was using 2.6   I could
not be sure when this would be fixed and could not wait
-3- the data service uses UDP to broadcast, not AppleEvents
-4- low traffic rate for UDP is about 150 packets per second so that I do
not have to worry about "not being able to receive fast enough", thus lost
data is due to problems in my code

Most programmers I know get confused with AppleEvents.   I am not sure why
but they think they are mysterious and give up on them.  With the
AppleScript language, however, I spend half of my time wondering why they
came up with this syntax, and the other half trying to figure how to make it
do simple things.

It would be cool if you could make some useful example stacks that would
show 3 apps using AppleEvents.  I know Ken Ray has some good tips on his web
site, which I have happily used.

How would you use AppleEvents in your work flow?
