[Evolution] Can Evolution write tasks to any remote type of storage?

[Chris G <cl isbd net>]

I'd like my wife and I to be able to share a task list but I can't see
any way to do this with Evolution.  Is it really not possible?

I can connect Evolution to a shared iCalendar file but it's a read
only connection which makes it rather pointless because one would need
to use another application to write tasks to the file.  One might as
well then use the other application all the time.

I don't want the task list to be 'out there' on the internet really, I
just want it to be on our SoHo server here at home.
