Aye.......

There are two non-Wikia versions of Monaco out right now:
 * Shoutwiki: We aren't worrying about this, but another rival wiki farm has Monaco. It, however, is a feature that must be paid for.
 * This port: The thing I just talked about is free source code with Monaco.

In conclusion: one is free (the one I linked to,) the other isn't.
