Is there a recommended way where you can use the full meteor functionality like collections, calls, sync, reactivity in other frameworks like Tizen Web?
Blaze at least seems to be useable: https://developer.tizen.org/community/tip-tech/using-blaze-templates-tizen
despite the recommendation on the tizen website the asteroid component is quite simple to include and provides much more functionality for connecting meteor applications from standalone apps or websites.
