Could you develop Snarl support for application xyz?

The concept of Snarl is application supporting Snarl and not the other way round. So it would be a good start to ask the developers of the application if they would like to embed Snarl support into their application. The developer community of Snarl will be happy to give as much help as needed to integrate Snarl support.
