using a DropBox based .ics file on my Galaxy.

[AC Question]

On our local network, we share a .ics file (sat in our Dropbox folders) to give us a shared calendar/task list - we both use Thunderbird with the Lightning addon for the PC and the Mac. It works really well, displaying changes in almost realtime, and the information is displayed constantly. We'd like to expand this to our Android devices. DropSync keeps the .ics on the device synched with the copy in the DropBox cloud. But I can't find anyway to read the file automatically, as Lightning does. The best I've managed so far is a one-off import. Ideally, I'm looking for an Android app that will read and write to this .ics file, not just do a one-off import.
Cheers
