Advanced Automatic Investor

I had actually thought of an online version before (but the trouble with an online AI is that I would then be responsible for everyone's data -- and that's a business I definitely don't want to be in). However, what you suggest would get around that if the site where you uploaded your aidb.mdb file was in your control and only the shell was in my control.

This sounds like something Google Gears is designed for.

Another alternative would be to put your aidb file on a thumbdrive (or email it to yourself) and take it with you.

A better scenario would be to install AI on the thumb drive. This would require a different licensing model where the license is not tied to the hardware.
