I'm much in favour of having an XML-based pipeline (both lxml and Genshi 
sound like they provide good tools here).

Gary Poster just proposed (see my response [1]) something on the 
zope3-dev mailinglist to allow standard browser views to return 
non-string objects which the publisher then adapts to IResult in order 
to actually obtain a string. For efficiently streaming large data to the 
client, this approach is already used internally in Zope 3: you write 
the data to a tempfile and return the file handle, the adapter to 
IResult streams the data in chunks.
