to the best of my knowledge, the next encryption added to MM will be Conax. This is being worked now and is necessary to keep the MM competetive with receiver firmware patches (i.e. Humax IRCI 5400), that support Conax already. As you might have heard or read, Conax, since recently, is viewable with season/ wallbanger/ appropriate CAM.
As far as Cryptoworks is concerned, there was a rumour / claim that one of the MM clones (Universal CAM) could decrypt this, but I do not think this has ever been proved true.
I am also not aware of any Crypotworks keys/ files available in the public domain.
