Well, it's possible to do if you are willing to do some legwork
yourself.  If you override the render method of your Page, you can
manually handle waiting for the Deferred stuff to finish, because in a
Resource's render you can return NOT_DONE_YET and then call
request.finish() at a later time.  I've done that successfully. 

nevow handles all this stuff much more smoothly.  I wouldn't put a lot
of work into extending woven.
