Besides ourself also Christian Heimes has done a more product oriented 
adoption of
the adapter and interfaces stuff. Will it be possible to use five in 
this way?

Will this monkeypatch be somewhat of a blessed way to include view 
adapters into zope2? Than we
can replace our current approach of using view adapters in union.cms 
with this one.
Or will this be integrated into Zope 2.8 at the end?

On the conference you suggested to setup a mailinglist for the 
discussion of interface integration.
Sure the main parts are done, but I think it would also be nice to see, 
how different projects are actually using the new possibilities. For 
example the usage of widgets can lead to something like a layout-manager 
or some other tools to really integrate them into Zope 2 applications. I 
think it would also drive some more testing and zope3 and further 
integration of other parts.

(If one has views, adapters, schemas and widgets, events are looming in 
the corner :-)
