Can you derive a ZClass in one product from a base class in another (separate) product? In principle, this is possible.
However, there are rumors (--> searchable mailing list archives) that the inheritance breaks when the product is exported and later reimported. The reporter concluded: effectively unusable.
Which begs the next question...
Can you search for multiple classes by searching for the base class. There is no buildin for this. But it would be possible to define such a search mechanism.
You would use "ZopeFind" on the "Products" folder to locate all ZClasses and then look whether the sequence of bases contain the one you are searching for. Dieter
