This is interesting to me...

I currently sync my iCal calendar (amongst other stuff) with my wife who is also my business partner.

My kGTD actions and the relevant calendar/contexts appear in her iCal and she either ignores/comments on/completes them and tells me/

It's not very secure or stable given that a sync back from her could delete things.

It would be good to be able to work with people who GTD (if that's a verb at all...) on shared projects.

But it would also be good to be able to work with people who don't GTD at all. A way of sharing and communicating without necessarily having open full and unprotected access to your GTD data.
