How about just a demoshield demonstration of it?

>We have an existing VFP 7.0 application, and would like to creat a demo version of it that we can put up on our web site, and have people download and install it. We would like to put some sort of locking/licensing in place to disable the software after a certain time period. The demo schema should not be able to be circumnavigated by simply back-dating one's system.
