[chandler-users] [interop] Which clients support Cosmo Ticket-based edition of collections on Chandler Hub?

[Graham Perrin]

Use case:

1. Two Chandler Hub account holders: Bert and Edna. 

2. Bert receives from Edna a view-and-edit /dav/ ticket for Edna's
'emeralds' collection. Bert adds emeralds to Bert's account.

3. Edna never discloses her password for Chandler Hub. 

4. In Hub: Bert pulls down the menu for emeralds, clicks the blue CalDAV
button, gains the 
/dav/collection/uid?ticket=ticket ticket 

5. Knowing that CalDAV us well-suited to editing, and knowing that (in
Chandler Hub) Bert can edit the emeralds, Bert wishes to use a CalDAV client
(maybe, iCal or Sunbird) to edit Edna's emeralds.

6. Bug, or misunderstanding, bites!

[√] Bert can use Sunbird for CalDAV edition of any/all collections on the
Hub that were created by Bert.

[X] Bert can _not_ use Sunbird for CalDAV edition of other account holders'
collections on the Hub, even though he does have edit privileges for those
collections.

A guess: as Bert's Sunbird sends Bert credentials to Cosmo/Hub in relation
to any Edna collection — with or without ?ticket= tail to the URL — so the
Hub's response to Sunbird is unacceptable. DAV_NOT_DAV or whatever.

A question, probably answer A, B or C. 

Is Bert's wish to use Sunbird for this CalDAV edition unrealised because: 

A) Cosmo/Hub will never, or can never extend an edit privilege in this way
to a CalDAV client

or

B) this Cosmo/Hub feature is on a wish list

or

C) Cosmo/Hub offers the feature, but Bert can not find a compatible CalDAV
client?

Advice will be greatly appreciated. The names are not real but the case is
real, and current.

An answer to this should be a near-final piece in the jigsaw to me rolling
out Hub services to my colleagues. 

Thanks!
Graham

That was probably my mistake: AFAICT, a ticket that is intended to grant
edit privilege does not, on its own, allow edition; the receiver of the
ticket _first simply views_ the collection _then must log in_ to Chandler
Hub if they wish to edit.
