Is there any interest / value in making jBPM tasks or process definitions visible / accessible via WebDav? With a simple change I found that I can list tasks (as .ics) in Windows XP Web Folders.
Testing your taskcal component is something thats high on my to-do list. After the community day, I'm going to give it a spin and give you some feedback.
I think that having the tasks in a folder can be a nice feature (altough I don't know about the 'real' use case). Ofc, if it's easily done, why not ;-)
