I am looking for a messenger or chat application, which should fulfill following criteria:
- Peer-to-peer serverless application.
- No login required.
- Should search and display for other users (running same app), in particular network.
- having very small GUI.
- Give instant pop-up on any message.
IP Messenger (in windows) is perfect example which I have seen, but its performance and GUI are NOT good in Linux (GIPMSG - Gnome IP Messenger).
I have tried messengers like Empathy and Ekiga, which comes with the distro, but the problem is they all need login and GUI of those are very large.
