i am familiar with erlangs ports. why shouldn't the same work for node?
(and btw: cryptography might take a big computational chunk. it's hard to write cpu-intensive stuff in node's callback style. but i guess the person(s) doing it will sort this out.)
I'm just explaining one motivation for wanting to be "pure". Node could certainly do something like what Erlang does. Erlang has, in the past, also gone the 'pure' route. IIRC, they had their own slow/limited regexp implementation, for instance, so that it'd run in the VM and not block.
