Hey out there,
transWhat: " ... transWhat is a WhatsApp XMPP Gateway based on Spectrum2 ... "
(https://github.com/stv0g/transwhat/blob/master/README.md)
Yesterday the author released the sources under the GPL at github: https://github.com/stv0g/transwhat
I'm not capable of adding this transport to the kraken gateway, so i was wondering if someone else might be? 
Even though it's not based on kraken, it would be awesome, having a whatsapp XMPP transport, would't it?
Anyway, i hope someone here is going to add it if possible, thanks!
Martin
