How do I use Android Market and SlideMe at the same time?

Background:

I sell an app in the Android Marketplace, and am looking at moving from copy protectio开发者_运维知识库n to Android Market Licensing. At the same time, I want to make the app available in SlideMe using their Slidelock licensing.

Questions:

What is the easiest way to implement two different license schemes at the same time?

You could do a check on both protection mechanisms and allow the app to run if at least one of them passes.
