Use MessagePack for event dispatch to server

[molind]

There is a great binary format similar to JSON: http://msgpack.org and it have node.js binding: https://github.com/pgriess/node-msgpack

I think it would be great to add binary event endpoint (http://serverName.com/b for example) and receive events as content of HTTP POST requests.

If anyone could implement this server enhancement i'll send patch for iOS SDK with MessagePack support.

Node binding seems to be slower than default JSON methods (5x and 3.5x). It would definetely help reduce the network transfer but it would cause a decrease in server performance.

MessagePack work very fast for large amounts of data, but sucks on small chunks. May be it could be optional? Some servers suffers from small bandwidth but have a lots of free CPU power at the same time.

Currently json implementation is used quite a lot through all the code, so it would be lots of changes to the core.

As this also concerns SDKs (many of which are managed by different developers), I really don't see this as an option for now.
