I don't have the time. However, I would urge you to think about an=20

Well, we simply provide the lowest layer. You easily put your own layer on =
top=20
of it. However, I would not want the Zope core support to ve specific to on=
e=20
of these frameworks.=20
Also, the new ZCatalog (namely ObjectHub) is ultra-flexible and you can do =
all=20
these things.
