It would be interesting if other android market apps could buy or lease the
rights to the License Server or have their market checked just like it does
the google market records. Im sure if google wanted they could find a way to
make that work.

I'm not sure that this is inherently insecure. Yes, it does use 
libraries and a public key that will be embedded in the application, but 
public keys are designed to be shared. All the client side is doing is 
verifying information encrypted with the private key which isn't 
accessible, and providing that information to the application for it to 
manage as the developer decides. I may not have my security "A" game 
going today, but that sounds reasonably secure to me. The private key 
isn't even made available to the developer as I understand it, so the 
developer doesn't really have the option of shooting themselves in the 
foot with it.

As for detecting rooted devices... I have no idea. :-)
