Simple node.js compatibility layer for vert.x (work in progress)

A little explanation in the README would be nice.

vert.x seems to be a node.js like solution running on the JVM (as opposed to V8), offering multi-core concurrency.

It doesn't appear to have any significant traction yet, but that may be because it's fairly new.

If you're considering this, be aware that writing JS that takes advantage of new JS language features in v8 and not present in IE/Rhino is not considered bad form in the node.js community. Also, Rhino is ~50x slower than v8, which doesn't show up in microbenchmarks but probably will if you write any real code with this.

I'm waiting for Nashorn to try messing with vert.x/js but that still seems to be in stealh mode.

Last I heard Rhino master was about 10x slower on average, not 50. For most real world applications it doesn't make much of a difference, since you spend most of the time waiting on I/O. Here are some benchmarks I put together comparing V8 (Node) to Rhino (RingoJS): https://github.com/olegp/common-node#benchmarks

I've implemented the inverse of this with Common Node (http://olegp.github.com/common-node/). Common Node lets you run synchronous looking code compatible with RingoJS (server side JavaScript on the JVM) on Node.
