CGI is preferrable to my POV.

MaxClient  10 will be good starting point

Anything you know good. DB don't seem to be bottleneck in this case.
Note, NOSQL is trendy those days. If it meets your requests MongoDB have
nice Python bindings.

Prototype, run simulations, and then you'll know demands better.
