Here's an interesting new technology by a company called "Pieceable." The idea is simple and is similar to what Amazon is doing with Android Apps. Developers upload their apps to Piecable and Piecable creates an embeddable Flash application that runs the app. It sends back embeddable code at three different price tiers for developers to embed in their web pages. For the most part, the applications seem to work pretty well.
"No code changes need. Just build your app for the Simulator (rather than the Device), and upload your .app to us. We give you back a link to your app on the web.
Easily integrates into your build process."
Pieceable Viewer works with most iPhone applications. If you have a native binary that runs on the iOS Simulator, it should run in Pieceable Viewer.
