VoiceMail VS Minivm(*)

I am curious if anyone has looked at implementing the minivm modules verse the somewhat inflexible voicemail module we currently have ??

I have been looking at the Module(s) documentation and there a number of nice features in the MiniVM modules that are not in voicemail. Including the ability to vary email and pager templates by user or group of users which while theoretically supported in the voicemail application, it is currently broken because of the way voicemail loads context labels and sets defaults.
