I don't agree really on your definiton or usage of "hybrid". For me, your are just a different form of hybrid. Let me explain: With Phonegap the "shell" or container is native, the rest is webview. So this is "hybrid".
If I got your approach right your container includes a bigger bit of native logic and you sparkle some smaller html webviews through the apps. So Phonegap apps tend to be "little container, much webview" while yours are more "much container and app, little webview". Correct?
But this is a detail, I still like the concept and page.
