Yes, ZoomRaster can answer mouse clicks.  Heatbugs does that; right 
click on bug to get a probe.  I used that in my version of the Conway 
game of life to let people create starting conditions. I think also it 
is in the Schelling segregation model. I recall that in the Opinion-2.0 
code, there is a thing where you can click on points in the grid and 
some info gets highlighted.  If you dig around in 
http://lark.cc.ku.edu/~pauljohn/Swarm/MySwarmCode you will find those 
things.

Sorry, can't help with that much.  I'm not a programmer by trade and 
when I hear them talking about these things, I don't really understand 
until I make the investment to actually make these things work.  I know 
for sure I've seen Swarm models run in web browsers, and it has been 
done through several separate avenues.  The newer swarm snaps have some 
COM/DCOM stuff Marcus Daniels worked on.  I know other people have 
written their own connectors between Swarm and the browser.
