Don't know if it would be that helpful to make it completely OpenSource or if this just would make it easier for WhatsApp to detect if it is an official or our client. Maybe we can "just" share the code/information to some developer wanting to create an client for other platforms?
But that are just my thoughts and it is tgalal who has to decide it because he is the only one having the source at the moment

In total I'm really looking forward to see an working version
Is there any status update you can give us tgalal?

(Oh, I could also help with a german translation but I think we are far away from translating, first we need an working version)
