Distributing an appliance

I have written an application which treats a computer much like an appliance- in most cases, the application will be set to automatically start whenever the computer is turned on, and the computer will not be used for other purposes. I'm trying to figure out how I can distribute this application so that users can install it themselves. What are the legalities of taking a current SUSE distribution CD, making a few changes to it, and selling it to customers? And how do I get the phone number of someone at Novell to ask this question of? Or, perhaps someone has a suggestion for a novice-friendly distribution I could use for this purpose. Thanks. Rich
