[ZODB-Dev] [RFC] ZEO: Allow non-packaged products

[Vincent Pelletier]

Hi.

I need ZEO to be able to find non-packaged products for conflict resolution 
purposes. As ZEO AFAIK doesn't support this I gave it a quick try. I reached 
the "works for me" state, that I now would like to get feedback on.

Basically, I transposed Zope's "products" config option to ZEO.

Did I miss anything already existing to achieve this ?
Is such change (functionality-wise) welcome in ZEO ?
If it is, is it acceptable in its current form ?
