Zimbra sync

[Störm]

I have searched, but failed to find any mention of syncing tasks to a
Zimbra server.

Myself and all my colleagues use Zimbra, and we don't mind using
different apps to access and manage our data effectively, but need to
access and manage tasks there.

So far, besides a limited view of Zimbra tasks using Zimbra mobile web
access or Aderium's limited Zimbra app, we can't sync or manage tasks
on my

Zimbra makes tasks accessible in iCal format.

Perhaps it is already possible to access them in Astrid?

I would be grateful to know in any event. :)
