[Zope3-dev] updated ObjectHub proposal

[Gary Poster]

OK--newer ObjectHub proposal ready for comment.  All pages that I added last
night have also been updated.

As I warned before, I'm afraid I wasn't really ready to unveil it, and so it
has several half-baked elements, some of which you all have already caught,
and I have fixed.  A number of important elements to the design are not
worked out or extremely vague, and may prove to be impassable roadblocks.
The split between the behaviors and the data jars seems very problematic and
inelegant to me right now, in particular, the deeper I think about it, but
the goal seems worthwhile to me.  Ideas?

In any case, only a week away from the sprint having to do with this, the
best I think I can hope for is to offer some new ideas and design
considerations.  And there are some reasonably good new ones somewhere in
there, I think.

Enjoy.
