Ling is cool stuff, but I have the impression that it's a clean-sheet Erlang VM implementation, not a port of BEAM. BEAM is time-tested and battle-proven, and I'd really like to see BEAM itself rely less on the underlying OS (e.g. epmd as a separate OS process, quirks in how it uses select/poll). I know Peer Strizinger did a lot of work on this[0], but hasn't (to my knowledge) yet released any of his work, sadly.
