I believe it will be better strategy for Meteor team to work and integrate their server with native Android/iOS app instead of Phonegap.
2. Also it is difficult to understand how Latency compensation will work. Does local in-memory copy of database work with Sqlite or does meteor install mini-mango on Android/iOS?
3. The author in the blog has written that they have improved the login by redirect based oAuth login in WebView. Webviews are surly not optimized for mobile devices and gives horrible user experience. If webviews would have worked there was no need for facebook to rebuild the HTML app.
Meteor team is far from providing a unified platform which can be used for Web and Android and iOS. It is good only for web.
