I think you're right Kristopher that there is something in the TOS.  But, 
seeing as how we all know Google can decompile any app it gets anyway I 
think there's also something in the TOS that binds Google to protecting 
your intellectual property.

But hey - if it prevents people from swiping a paid app then I'm all for 
that kind of thing.

I believe Google and Amazon have invested quite a bit of money to protect 
apps.
