I do have a toy project that aims to be a cross-platform Ejecta eventually. It's written in C and divided in an OpenGL Canvas drawing library (so you essentially get the HTML5 Canvas API in native code) and a host application that provides the JavaScript binding.
Currently, there's only a host application for iOS. I don't know much about Android and have yet to figure out how to best couple the C lib with the Java code... or if I even need Java code to begin with.
I wanted to have a working Android host app first, before putting it on github and then building up the feature set on both platforms to where Ejecta is now.
I also thought about doing a kickstarter for this, but I'm not sure what exactly I could "sell", because the I want to have it open source anyway. If anybody wants to sponsor the development, get in touch :)
tl;dr: yes.

It's based on Chrome for Android so you have a fully-featured browser engine available. iOS is the only platform where there isn't a good GPU-accelerated browser engine available that can run native apps, hence the use case. (P.S. we hope to support Ejecta in Construct 2 officially soon!)
