Hm. why "wait for ZEO"? I think you can use ZEO right now for
this. A common usage is with DBTab (included in Zope 2.7, installable
for Zope2.6) to have specific root storage for each site and
one or more shared stores for resources you want to use
in every site. This way you dont have to copy or sync - the
objects are available instantaneus.
