Which year it was? I think I had working synchronization between Gajim, Psi+ and Dino. Don’t remember if Conversations fits into this list. There’s a XEP for this supported by them so it should work.

XMPP is modern XMPP replacement.

Had a nice TV from that company. It was really long ago, though, and the terribly bright blue indicator of it being on I didn’t like, especially when using as a PC monitor.
