I'm doing some serious digging around in the XBMC player classes to see if this can be improved on, to actually decrypt the content using XBMC's player.

Actually, this sounds like an interesting approach. Did you find anything in the player classes that would allow an on-the-fly decryption? Where exactly are you looking, maybe I can also take a look?

I couldn't find any class methods that you could tap into from a plugin. Any changes would have to be made to the XBMC source.

A cleaner approach might be to have a plugin (or a piece of code) act as a proxy server that decrypts the stream on-the-fly.
