Vidibus::Permalink 
This gem allows changeable permalinks. That may be an oxymoron, but it's really useful from a SEO perspective.
This gem is part of Vidibus, an open source toolset for building distributed (video) applications.
Installation
Add the dependency to the Gemfile of your application:
gem "vidibus-permalink"
Then call bundle install on your console.
TODO
- Add controller extension for automatic dispatching.
- Limit length of permalinks.
- Refactor codebase so that incrementation is not limited to Permalink class.
Ideas (for a separate gem)
- Catch 404s and store invalid routes.
- Make invalid routes assignable from a web interface.
- Try to suggest a matching Linkable by valid parts of the request path.
