Can a Meteor template be packaged up and deployed as a PhoneGap application?
Well, I guess the best starting point is figuring out how far you want/need to go.
Would you want
A Meteor.js PhoneGap app that connects to a server somewhere? Then you´d probably want to use the Meteor classes in a PhoneGap project and connect to your server with Meteor.connect(url).
Offline App data persistence - That´s gonna get tough... That´s not
something Meteor was designed to do, although there surely are ways
to achive it. I remember that discussions from backbone, spine and
other client side JS frameworks. It´s easy to use local storage, but
the real effort there begins when you want to sync data between local
and the server.
That should help to get to the point...
