sorry i can't trust you on that one, because i am involved in a very
big project at the moment. i'm not allowed to talk about it yet, but i
is probably the biggest application of python in austria (ok, that is
not really hard ;) )
and i wrote a similar service (but way not as large) with nevow's
traditional way of dealing with urls. and this one is very hard to
maintain, because the url system is not abstracted out of the code and
templates.
so maintainability IS the reason i use a django like url dispatch
system. i'm not a native speaker so convenience was probably the wrong
word to choose.

but it very much depends on the type of project. for some projects
(also relatively large ones) it has been the right decision to stick
with nevow's default way of handling urls.
