My advice is to invest now and build your own tool for scheduling and use your server or database for security. Seagate Info is really hard to customize. If you want to validate parameters or do any GUI stuff before the report is called, Info will be frustrating. On the other hand, if you write a simple VB app. you can set it up to do exactly what you need. I'm not sure how expensive it is to buy VB and distribute VB apps, but I think it's well worth it.
