NateOn is the instant messenger created by SK Telecom, for Koreans.
However, it does supports Windows only as main platform.
I've just found some projects that provides a way to communicate with NateOn under Linux.
1. For Mac / Linux (Gnome users):
- JateOn, written in Java (Swing, SWT required): http://jateon.kfmes.com/viewforum.php?f=4
It's still being developed.
- NateOn plugin for Pidgin: http://nateon.haz3.com
I don't think it is under development anymore....
2. For Linux (KDE users): this is the best choice
- NateOn Linux (current version 1.0 beta): http://nateonweb.nate.com/download/messenger/linux/
It's best if you are using Fedora, Gentoo or Ubuntu because the installation package is done, just one click and run. Other distros might need to download source and compile.
3. Using WineHQ to emulate:
- Some notes on experiment can give you a hint. You might want to give it a try: http://appdb.winehq.org/objectManager.php?sClass=version&iId=7524&iTestingId=11299
If you know any other, please notice me!
