Hi, As GSoC is coming to its end, I'd like to present you the Pipeline library: code: https://github.com/erenon/pipeline documentation: http://erenon.hu/pipeline I'll continue to work on this project, the next big thing is to implement a coroutine based execution. I hope using cooperative scheduling will enable a much better throughput/latency combination over the nice and easy to use interface we currently have. Thanks, Benedek
