Development status : Toy. Works for me, and it supports the protocol COPY command too, which is nice.
Motivation : I wrote this library as a proof of concept and to learn a bit more about different TCP protocols. The main (only?) reason for wanting to do this is to be able to write an "Event Machine" / "Twisted" type of server where you can do asynchronous I.O. to several different kinds of application endpoint, e.g. RabbitMQ, Postgres, MySql, HTTP, etc. etc.
Future : Currently, and for the forseeable future I'll be devoting my "open source" time to my Amqphp project, but eventually I'd like to expand this to be a fast, fully asyncronous, PHP-implemented "business process server".
