I see two options:

  1. you explicitly pass the data around via return value and parameters

  2. you put them in the "REQUEST" object

Both ways are restricted to a single request processing.

  ZSQL results are too complex to be stored in a (standard Zope 2.5) session
  object.

ZPT namespaces cannot be used to pass information from inside a
script to the ZPT implicitly, you need to return the information
as the scripts return value and bind it to a name in the ZPT namespace.

I am not sure whether the ZPT namespace is automatically passed to
Python Scripts when they bind the "namespace" binding variable.
It may be the case. You can go via an intermediate DTML object,
if it does not work (though I do not recommend this way).
