[Zope-dev] ZODB3 Q

A few Q's on the new ZopeBase for any takers. 1) ZODB3 supports multiple concurrency. Does this mean that an application can have transactions running on different threads AND multiple application processes may be running? If the latter is possible, is it possible using the present ZODB classes (I noticed there was one for 'distributed filestorages') or possible only by supplementing them in some way? 2) Can ZODB be easily used independently of Zope? Is there any sample code for such a thing?
