Hi Folks,

I, too, am late to this thread, sorry.

I'd been envisioning a slightly different picture of how we'd render
different versions of what, in the user's mental model, is the same
item.  Changes received via sync seem like a special case of the general
problem of several people editing the same (mental model of an) item.

==> As an aside, I have a suspicion in some cases we'll represent
different versions using versioning in the repository, at other times
we'll have different (linked) items under the hood, to match the
"emailed item" model where there's no authoritative source of truth.
I'm going to approach this by assuming we can work out the
representation issues. <==

Here's my picture, based on what I think I've understood Mimi to be
describing about scheduling workflow.  If an item has multiple versions,
the most recent version would show up in the table view, but it would
have a thread expansion widget associated with it to open different
versions in the table view.

This would avoid the need for multiple detail views; users could scroll
through different versions in the table view.  It would be nice to
highlight changed fields to call out distinctions between versions.

To do this at a basic level, the table view would need support for
something like threads.  I don't know if that's doable in 0.7, but it
feels like a more appealing path to follow than trying to render two
detail views.

In this model, there could still be an RSS style view of recent changes,
 it would be basically look like sorting a collection into threads
sorted by an imagined "last time modified by someone other than me"
