[erlang-questions] Webmachine Binary Request Strings

There was talk on one of the mailing lists about using something like
SimpleBridge (https://github.com/nitrogen/simple_bridge) so that the use of
a web server could be independent of Webmachine's logic, which IMO is the
best solution.  I don't think anyone did anything about it, but for some
reason, SimpleBridge has Webmachine support, which doesn't make sense
logically to me since Webmachine is a toolkit and not a web server.

I use Webmachine and love what it does for me, but the code seems overly
complicated with a heavy reliance on Mochiweb and uses parameterized
modules (an unsupported feature of Erlang), so I would actually be more
inclined to start a new project which is influenced by Webmachine but
corrects all the issues with it and makes it a bit more flexible and modern
(would love for Webmachine to support PATCH for example and something like
Socket.IO).  I'd be happy to help out with such a project if anyone is
interested in starting one.
