Not every admin has the time to implement a new ejabberd module that
does IBB checking :) Most will just disable it and done. So this is
very admin and therefore user unfriendly. That's why we shouldn't use
Jingle IBB, but something else, so it's very very easy to distinguish.

And no, if it's encrypted, I can't say what is in it!
