It started with this post:

and it looks like it is going to happen:
Does this mean it will be possible to interop with Armory in OpenFL ?
Somehow in a mind boggling way, probably.
Will have to see how it all works, but since Armory is mostly a regular Kha library it should be doable! 
That would be great to get more people to bridge over from OpenFL, I use it myself and lots of people on those forums use it for games creation, etc. It is a great community and the possibility is just awesome.
