"Instant messaging" in general is a really crowded field of endeavour.  The IETF had nine different protocol proposals in fromt of it.  After a heroic effort these reduced to three.  Now JABBER is attempting to expand the field again.  The IETF has defined a framework for presence and instant messaging to make it easier for all of them to interwork.  I suppose at some point we should look at how T.140 might be brought into line with this framework.

What's the difference between "instant messaging" in general and T.140? IOW, what can you do with one that you can't do with the other?
