I see the support of the python datetime class, and read through the pb-copyable howto, but am still curious if there is a way to make a module classes jellyable (specifically mx.DateTime) without writting a wrapper class? My postgres database wrapper returns mx.DateTime and a lib on the client side expects mx.DateTime so it makes sense to keep it in that format. I saw a message back in 2004 about working on the ability to register external serialization functions for new types. Is that in place now? I have seen some chatter in previous posts about mx.DateTime but could not find a definitive answer. i.e. "don't hack it, make it work without mx.DateTime", or "philosophically, what your doing would be insecure and not cross-language compatible (which pb is), hence your question is void.", or hopefully "check out xxx for external serialization" Thanks --gabe
