[ZODB-Dev] [ZEO] Weakness introduced in ZODB 3.2

[dieter at handshake.de]

Dear ZEO maintainers,

I just recognized that ZEO grew a weakness with respect
to application specific conflict resolution with ZODB 3.2.

Classes requiring application specific conflict resolution
are sometimes tied to a product (e.g. the queue class in "QueueCatalog").
Naturally, they are then defined inside this product.

To perform conflict resolution, ZEO must be able to import the
respective class. To set things up such that ZEO can import
classes in a "Products" outside "lib/python" is very difficult
(I do not know a solution).

Before ZODB 3.2, ZEO interpreted "INSTANCE_HOME", but this is no
longer true for ZODB 3.2.


We need again a way to allow ZEO the import of classes defined
in application specific products.
