Konnection is a GUI replacement for pon/poff I made for my personal use. Maybe you'll like it, too. It shows your Internet configurations from /etc/ppp/peers/ and lets you choose which one to connect to.

Installation:

For HD Install users:
su
apt-get install gambas-runtime gambas-gb-qt
# download .deb from http://klik.berlios.de/konnection/
dpkg -i dpkg -i konnection*.deb

A klik install could follow if there is enough demand.

This is a 0.2 release, so I'd appreciate feedback.
