License/Registration frameworks for OS X development?

license/registration/serial# frameworks for OS X?

Are there any well-regarded licensing/registration frameworks or libraries for OS X development? For example, we have Sparkle as a widely-used software update framework that lots of folks use. I'm wondering if there's something similar for reg codes/payments/etc. Thanks in advance!

Remember that there's really two parts to this. One is the registration dialog that lets you input your information to pay for and/or register the app. The second are the calls to check whether you're registered or in demo mode and act accordingly. The first part can be delegated to a 3rd party framework, but second part is all about clever, custom obfuscation techniques to frustrate crackers. Even Allan Odgaard's public key crypto approach just protects you against pirate license keys, but not patched binaries.

I was going to mention Golden%Braeburn but I see it's mentioned in the SO link above. It was written by Wil Shipley of Delicious Monster fame.
