[Zope] Mapserver and Zope

Hello, I´m trying to use Mapserver -- a open-source GIS-tool -- inside Zope and I would be glad to get some honts of some who have experience with that... I have already "swigged" mapserver to Python and now I think I have to wright Python scripts to access the methods/functions in the mapserver-library. Finally I have to add these Python-scripts as External Methods into Zope... Has anyone tried to use mapserver with Zope and is able to give me some advise whether my plan above is correct or totally rubbish.... Thanks in forward, Sven
