Jeff Benjamin on his personal blog:

That’s all nice and all, but the real meat an potatoes of Ashes’ new sharing options aren’t even mentioned on the app’s recent changes list on the App Store. The big new feature here is support for something called Share Anywhere, which lends the ability to dynamically add additional functionality to Ashes on your own. This new feature allows you to potentially share with any app that you choose, as long as the app supports the openURL protocol allowing for inter-app communication.

Jeff has a thorough rundown of all the great stuff in Ashes 1.1, my favorite Fever client.
