I know that I have been asking before, but I haven't seen any update on the issue. Is there plans to give CalDav support? Seems like more and more CalDav is becoming a standard. Even MobileMe, Yahoo, Chandler project, are all supporting CalDav for tasks. It would make easier for developers to create programs to access Toodledo and use the existing ones (like iCal). Tasks are supported by CalDav standards. For instance, Yahoo can sync tasks with iCal besides calendar appointments.
One calendar map to one folder in Toodledo would be great.
Think about it.
