Certainly.  At this point it's still in development, but I think that
DOMtemplate could be modified to support Deferreds pretty easily (after
all, it's almost like WebWidgets, except instead of returning lists of
Deferreds and strings, it returns lists of Deferreds and Nodes).

I may even get around to doing this :-).

As far as threading goes -- we need a threadsafe version of web.Request,
and a way to dispatch requests in an MT way, yes, I agree.  The fact
that this is inefficient should be offset by the fact that every other
web-app framework in the world is at least 3x less efficient than _that_
