[Design] Reconciling sharing privileges with the Edit / Update workflow

[Jeffrey Harris]

Hi Mimi,

It would be reasonable for Chandler to create personal tickets (or did 
something analogous using whatever permission approach we come up with) 
for each recipient of a shared item on that item.  Then capital-N 
Notification emails would need to be individualized, so they could 
include the relevant ticket.

This would be slower than sending the Notification as one email with 
lots of addressees, and the semantic information about who was notified 
wouldn't appear in the normal place (the address fields).  But that 
doesn't seem all that bad, we're talking about small group 
collaboration, someone planning a wedding might have performance issues 
Notifying their entire guest list.

Sincerely,
Jeffrey
