You can just return a dictionary from your external method and use the 
<dtml-in "externalMethodName(1,222)">.  inside the dtml-in tags you can 
reference the index or the value of each dictionary item using tags like 
<dtml-var sequence-item> , <dtml-var sequence-value> ( double check this 
syntax in the DTML guide ).

Basically, anything you can do in Python CGI you can do in Zope.  Take a 
look at DC COM Product.  May be just what you are looking for...
