Routing question

Hello

Given the following rules

MyApp::Application.routes.draw do |map|

    resources :accounts do         resources :comments     end

    match '*path' => redirect("/accounts/%{path}")

end

Can we get ActionDispatch to, rather than redirect, re-run the routes? This would come in handy for using account handles, as in

http://mymusicwebsite.com/metallica http://mymusicwebsite.com/metallica/comments http://mymusicwebsite.com/metallica/comments/2

rather than

http://mymusicwebsite.com/accounts/metallica http://mymusicwebsite.com/accounts/metallica/comments http://mymusicwebsite.com/accounts/metallica/comments/2

Any help appreciated.
