While i'm not a huage fan of KDE, as i'd prefer Phosh, this is still great news. Seriously considering pulling the trigger on a PineTab-V although i'll probably give this a bit of time to mature.
I use Pragma-Messenger. It's based out of Switzerland. Never seen it go down and I use it daily so i'd call it stable. The site's in German so you may have to use a translate extension in your browser if you don't read German.
Red Eclipse or Xonitic for me
