1. X/GTK-based internet telephone. Gphone is an internet telephone. As the name implies, it aims to be fully gnome-groovy, but that hasn't quite happened yet. Gphone is definitely a work in progress and you probably shouldn't bet your business on it. Don't be too hard on the program, though -- although the user interface is mighty rough, gphone does actually work pretty well. The data rate should be low enough to work over a reasonable modem connection. The protocol is nominally RTP/RTCP, and gphone complies well enough with the standard to be able to talk to speakfreely.
