The proposal assumes a slightly deeper understanding of the Mono
"mono runtime" is here the part of Mono that provides the OS
abstraction layer (file, network etc.) and GC. It's that minimal
part of Mono that's needed for running static AOT (ahead-of-time
compilation) assemblies that were compiled to native shared objects
or included into the main executable. Basically, it's Mono sans
code generation, suitable to run on the target.
The target is here "emscripten/asm.js", so it needs a port.
"mono cross compiler that can target emscripten"
is a Mono LLVM AOT target that generates LLVM code suitable
for emscripten. This part is supposed to run on the host, i.e.
it has access to a full tool chain etc.

The forums are just a mirror of this list.
