Dynamo.Filters.MethodOverride

Hi. How do you think about having Rack::MethodOverride kind of feature, like the Sinatra's :method_override?

I was playing around REST-based object manipulation, and needed to write a filter for using PUT/DELETE methods for HTML form submits.

As it may be relatively common scenario, I'm wondering if it could be included as optional feature (enable by - filter Dynamo.Filters.MethodOverride, or something).
