This is excellent :) I just wonder how it compare to DDP (Data Distribution Protocol) wich seems https://meteorhacks.com/introduction-to-ddp.html http://en.wikipedia.org/wiki/Distributed_Data_Protocol ruby client: https://github.com/tmeasday/ruby-ddp-client <https://github.com/tmeasday/ruby-ddp-client>
Thans by the way, I’ll try Simple DDS.
