I read this would make it iCal compatible. Would this allow it to be imported as a shared calendar in Google Calendar?

I think RSS feeds should be created on subtask trees. i may want a certain group of people subscribing to a tree or two of tasks and subtasks, but not the whole list. I know the solution might be to have separate tasks lists but i prefer a few long lists over the many many short lists. Can this be implemented?

very good idea. Should be easy for these brilliant developers. I hope we can create RSS like the due date by ending with some sort of rss command. That would allow multiple RSS feeds per page. Not all users in a shared list will care about all tasks. ALSO, iff there are sub-tasks you could plant the RSS at the right level that makes sense for you. In other words if you have 4 levels of tasks you may find a spcific BRANCH that needs an RSS feed for a small team that has actions on that branch and needs to see the NOTES and task status via RSS. I like it. I wish I could vote more!
