[jdev] Threema using XMPP

[Simon Tennant]

Threema is a very popular and [claimed to be] secure messaging service in
the German speaking countries.

It was just pointed out to me that it's also using XMPP and has 2.8 million
users.

Does anyone have contacts to the team behind this? It would be great to
have them do a write up for the XMPP.org website if we can track someone
there down.
