Blueprint test environment online (idea)

Hey Epic / Unreal Community,

So i’ve been toying with UDK / UE4 for about two years and have been fascinated with Blueprint scripting. The problem is that most of my day I’m surrounded by devices that can’t run UE4 - like my work laptop or my cell phone.
I thought it’d be a cool idea for maybe a future version update of the Engine to release something that would let people play around in blueprints - and just blueprints - to get used to seeing what properties expand from what nodes, and seeing if things would compile - but not actually effecting anything in 3d space (to keep the size and simplicity of the program down so that it could be on a phone maybe).

This way someone could mess around with Blueprints on a subway train and then test things out when they get home.

Just a thought! Either way, love love love UE4 and cannot wait to develop something awesome with it!
