Send-in-time statements are the best approach now but risk locking out 
mouse events. The pseudo-threading I wrote about two days ago handles 
this type of programming easily from both a technical and coding 
perspective. In HC I have a 'Beer game' which demonstrates it - supply 
and demand shift in the background and provide graphical reporting 
while you pull the levers of commerce.
