[Half OT] Sync Palm-Notebook-Server ? (Score 1)

Hi, I hop this is not OT, but I'm really looking for an "as open as possible" solution to set up a Palm - Laptop and Server sync. AFAIK I could use KDE PIM and E-groupware for example but I haven't tried yet and I don't know if there are other solutions.. like Opengroupware.. any suggestion? thanks, Marco
