Jeff is right on target. THE biggest issue I have with it is that one app never fits. There are ALWAYS an endless number of feature requests, and the license usually never takes these into consideration. Make sure that if you plan on doing it, and making changes, then you (a) charge for time, enough to make it painful ($150/hr or more), (b) are charging for time and that they don't own the code, and (c) limit the number of requests per day/week/month/year, etc, and (d) have the right to terminate the app, hosting, licensing, and support at will, and the only recourse they have is to buy it for a minimum amount decided by you. If they REALLY want it, they'll be willing to make concessions. If you go this route, you need to be willing to lose control of the app, and be blocked from the industry for up to three years. It will happen. Chances are they've looked for the app, even tried to have it written, and now they've found it for license, and a guy that's willing to keep it up. All that stands between them and the app is negotiations. We're not painting a pleasant picture, but we're holding back. It's worse than it appears.
