[Zope] Zope in transactional web sites

[Anthony Willoughby]

Hi

Apologies if this list is the wrong place to post this request.

I am looking for examples of cases where Zope or Plone have been used as 
the basis for transactional web sites - e.g. banking, shopping. 
Specifically, Zope should provide the front end to a transactional 
back-end, preferably processing medium to high volumes of transactions 
(5 - 10 million/year).  I have searched all the Zope related web sites I 
know but all the case studies provided deal with informational rather 
than transactional sites.

Any pointers appreciated
