I gave your code a try. Works after some tweaks and is really 
simple to use. Nice proof of concept. Performancewise you
lose a lot with many template pieces, because they are
not cached (I lose around 30 request / second even for
the simplest pages). Any chance to improve that?

Your code does also not conform to the Webware Stile Guide 
(I had to learn that too, because Chuck is quite strict on it. 
Reading Webware code is much easier if everybody uses the 
same rules, so it's really worth the time). If you need advice,
you'll get it :-)

Also names like

    def dfltTplSubst(self, tpl_name):
        tpl_filename = tpl_name.lower() + ".html"
        tpl = template(self.path)
        tpl.file("T", tpl_filename)

are not easy to understand (same for one character variable names ;-)
Most methods need a short doc string (especially template.py).

B.T.W. Plow = template? and what is Plow?

Ignoring all this minor details, the result shows how
easy it is to implement a simple template language.
I could live with your solution (a performance/Caching 
fix would be nice though..).

PlateKit from Tavis Rudd has other nice ideas
implemented (I have to look at it more deeply).
Is there a chance to combine the best of both worlds
(+ Chucks ideas on that topic, + zebra?) and bring the template 
discussion to an end?
