Can a Meteor template be packaged up and deployed as a PhoneGap application?
There is also this package: https://github.com/awatson1978/cordova-phonegap
I havn't tried it personally, but it seems the right approach.
Update: In the devshop of august, phonegap support has been announced from the core team with cool demos and stuff.
To play around with it:
meteor update --release CORDOVA-PREVIEW@3
