The source snapshots are now "Gnome2 ready". The code has been ported to GTK2/Gnome2, it has been cleaned and improved. You can now consider that GnomeMeeting is fully ported. The snapshots also offer a new configuration druid that will help you to configure GnomeMeeting following your connection type (among others) the first time that you run it.
If you are a windows developer, please contact me. The windows port of GnomeMeeting is in good way, but help would be appreciated. I'm not doing the port myself, but somebody is working on it since a few months.
