I love this. You simply create a symlink to your app, and boom, the app works at nameofthesymlink.dev. Even after a system restart. And pow is clever enough to only start workers if the app is accessed and shut them down when idle.
This is a blessing if you usually need multiple local apps running.
It also means you can now elegantly use local ruby webapps as personal desktop applications. Say you'd like to build a simple journal or expenses app to use on your desktop for personal use. You can now quickly build it with - say - Sinatra, Datamapper and SQLite. And no need to launch or quit it. Beautiful.
