Given Clients use OTR that would not matter as much, the reality sadly is that only few clients actually use OTR. (In any client I've seen this is turned off by default.)

We should certainly emphasize that updating ejabberd is _absolutely_ key to getting better crypto support for any (c2s and s2s) connection. Most ejabberd installations are somwhere between fairly to terribly outdated. (Seems people fear to touch it ever again once they got it to work.)
