Yep. I have one of those lists, too.

Given that Emscripten was used to port the Unreal engine, though, I'm
hoping that libtvm doesn't hide any complexity that would make this path
break. I managed, in the in-between minutes yesterday, to get Emscripten
installed on a VM; given how much time I have lately, it will probably take
a week (at least) before I know if this path is viable.

I'll keep the list appraised, obviously.

Agreed on all counts.
