I've actually been (slowly) building something based on Javascript/Node/NodeRed (check out my github - same handle - for a very rough start) for a game that I've been wanting to make. ( A real-time "web2.0" remake of dopewars...but with an actual persistent market and mechanics...with an Actor paradigm so you can run swarms of cops / thugs / bitches / arbitration, the works...all little javascript NodeRed clients running in the cloud...sadly not enough time on my hands to go it alone...hint, hint )

I'm definitely down with helping with anything in Erlang or Javascript.
