Sounds interesting!

My opinion: It isn't possible in to do it completely in Revo. A lot of 
your code will be totally platform specific. You will end up coding 
with device driver C/C++ interfaces in Mac OS or Windows. This article 
might be interesting for the Mac OS X side of things. Looks like voodoo 
to me...

On MacOS, if you had keyboard and mouse capturing, then you could use 
applescript to control most apps. Donnow what the equivalent, if any, 
is on Win32.
