I think that there's no concept of a message id like in email, but if so great, something to look at. > I have thought about ( not implemented ) this sort of reply > type system before.

Only becomes an issue if the transaction has more than one MT and one MO message really. The way around it I thought about before would be for the web application to increment some counter starting at 0 to indicate number of replies (read: inbound messages) received from a given number. But then how do you know when another transaction has started? Maybe reset that counter to 0. You're right, food for thought.
