Sounds like fun, except suddenly it's a web framework competition as well.
Which somewhat misses the point. Unless we specify one web framework, at
which stage there's an argument to be had about view processor and form
builder (at least under Catalyst, which does it's level best to not be too
opinionated about such things).

Better might be to do the Simplest Wiki Frontend Possible and define a nice
big back-end API with plenty of unit tests, then force everybody to code to
said unit tests.
