NimbostratusI've heard of lots of customers who have done things like this. The implementation would depend on the platform you are using. Building an ASP app would be a snap as you can just plugin the iControl Assembly (iControl.dll) into the project. Java is almost as easy but you'll have to include the other 3rd party libraries in the iControl Library for Java (iControl.jar) download.
The biggest issue I see customers face is with the topic of username/password security. You can store the credentials on your app server (in code, file system, or database) and make it a no-auth operation for your users or you can require them to login to your app and either use passthru authentication or do a authentication proxy where you map web server credentials to BIG-IP credentials.
