It is unusual for Apple to release beta products to the general public -- such software is typically reserved for registered Developers, however Apple surprised everyone with the announcement of  Messages Beta to all.

Perhaps this is Apple's new strategy, to be more open -- or devious?

Consomac (French site) have discovered some interesting text inside the resources file for the package.

Thank you for participating in the Messages Beta program. With the inclusion of Messages in OS X Mountain Lion, the Messages Beta program has ended.  To continue using Messages, please visit the Mac Ap Store and purchase OS X Mountain Lion.

An interesting find, and a perhaps a ploy by Apple to get you hooked on the functionality of Messages, thus forcing an upgrade to Mountain Lion when it is released!
