I think I'll stick with web apps for now :)

In that case you might consider the following:

1. client requests massive dataset
2. webapp returns a "processing started" message, starts job in new thread
3. data processing completes and a static file is generated

AND

4. a notification is sent to the client stating that the data is ready for download
5. client downloads static file, file is deleted

OR

4. file is emailed to client

And yes I used excel as the result. It is faster, but still can do better. I 
wonder if I can increase the process time to less than 30 min to produce 
results with millions of data. Currently, with only one person doing the 
analysis and no one else uses the app, it takes 2 hours to finish sending the 
data to customer screen.


Maybe you should ask yourself, whether a webapp is really the best
solution here.
It sounds more like you need a central business logic server and a
smart desktop app (swing or something) which can present the data in a
better way, as letting the customer wait for 2 hours...
