I see you've been sent an incredibly detailed response using a  
multipart solution, which probably works fine.

However, a different way of tackling this would be to use POE to  
update the page rather than fighting with timeout issues. If there is  
just one lot of modelling output shared by all users (IOW they don't  
provide parameters to it), maybe you could have the model constantly  

Have a look on CPAN for POE. I reckon it could be a good fit.
