What do you mean by anytime?

This request?

In this case use: 
  REQUEST.set('dictObj', dictObj) 
to store and 
  dictObj = REQUEST['dictObj']
to retreive.

For this user's session?

In that case use:
  REQUEST.SESSION['dictObj'] = dictObj
to store and
  dictObj = REQUEST.SESSION['dictObj']
to retreive.

Forever (including after Zope restarts) is a bit more involved, but in
the external method you could set it as as attribute of some object
(like the cmf portal or folder object), but that is a hack. It's easy
though in the ext. method:

  portal = self.portal_url.getPortalObject()
  portal.dictObj = dictObj

to retrieve (from a python script) use:

  dictObj = context.dictObj

If you want to do this the "right way" you should store the dict values
as properties or store the whole dict in a custom Zope object.
