This is a great discussion - I hope I haven't missed the chance to interact.
I had not thought about the fact that a full version might have trouble finding the preferences of the trial version.

I am wondering if the ANDROID_ID does have some value for paid subscription. If you are trying to tie a purchased license with a web subscription. Or if a Market purchase has already been refunded within 48 hours, but the binary has already been copied to various pirate sites, you may want to revoke the web privileges. But it's only helpful if: -Google Checkout can give you server side notification of the ANDROID_ID (Google ID?) at checkout and refund. Does it? -You can get to the ANDROID_ID programattically. -There is an ANDROID_ID for phones with no Market Access.
