The ipex isn't anything IP related, it's just the new mpd card emagen combo. They put an emagen on the mpd board and now it takes up 2 slots. I guess some people really wanted an inskin voicemail. Anyway, you should be able to use exactly the same updates on a stand alone as on the ipex. The only real difference between them as far as I know is the linux package distribution is different. Otherwise, they are just the same hardware in a different container. You might have your vendor call and ask if that makes a difference, but I'd be surprised if it did.
