One thing that is problematic today is serving large files
from the ZODB (ignoring the upcoming blob support).
Why would you ignore that?

b) If you dump the data to a temp file and return that as a file
iterator, it can potentially take twice the time.
OK, so?
c) If you use RESPONSE.write() you can break other
applications. ExternalEditor comes to mind.
I wasn't aware that it would break RESPONSE.write, but, in any
case, this will cause a tempirary file to be created.

I would like to be able to return an iterator that can read from the
ZODB. That would probably benefit the WSGI integration as well. Anyone
has ideas about how to solve this?
You could create an entirely new server with different thread-management
semantics. You could probably do this with the normal Zope publisher
using
one of the standard threading WSGI servers,
Or you could use a temporary file or wait for blobs.
