In case you were wondering why no update for so long...
Cepi's build is really good, I examined the code ups and downs.
Fixed a few really small issues, but overall it's great.
Some UI freezing might occur if you have a huge number of contacts, we'll see what can be done about that, those profile pics need to generate faster.
About sending media like images, audio or video:
I have the UI ready. Backend needs to be written in Python. However my knowledge of Python is as small as my experience in XMPP.
Any help to get this done quickly is vastly appreciated.
