Dynamic Animated 2D content from a remote server

I am thinking of making a UE4 app which can dynamically load 2D animation from the net and play it back with user interaction. I know that embedding a HTML webpage in the 3D world is an option but looks like this wont work on mobile platforms. And my app is aimed at the mobile platform. Maybe use paper2D flipbooks which can be dynamically downloaded from a remote web server ? Not sure about embedding Flash content or something similar.

One thing that has been established is that we cannot dynamically stream a level from a remote server and play… or has anyone manages to do that ?

Any help / suggestions will be deeply appreciated.
