GPE seems to be working really nicely here with OZ 3.5.4 on my Zaurus collie. I am using Sunbird Calendar (windows) at my office and the calendar extension in Thunderbird (Mepis Linux) at home. I have access to a server that supports webdav and save the calendar there from both locations so I have an up to date version of my calendar that I can read and edit from work or at home.
What I am wondering is whether there is a way to access the same calendar using GPE Calendar. Will it support loading and editiing a remote file in this way? It doesn't look like there is a way to do it but I thought I would ask here in case anyone knows a way.
