Without the ability to do "Full Control" from within MC itself, you're not going to have:
* Filesystem management (RMCF, essentially)
* File upload (for cover art purposes)
* View management
MC can already do all of that, so completely re-inventing the wheel seems... Silly. I recognize that some of that will take some extra elbow grease (particularly if the client and server aren't on the same OS platform). And, I think some view management (Theater? Media Network?) is actually stored in the Registry, even though they're considered part of the "Library".
Nevermind on that last bit. It works with my "trick" method.
