I tested the echo: in the slowdown fork. Works perfectly for replicatorg. I saw you asked kliment to imlement it for pronterface.

I also added the streaming lib in this fork; I've grown quite fond of it and use it a lot for other projects that require lots of of serial /ethernet communications. Might be useful for LCD as well.

This allows you to replace

serial.print("A:"); serial.print(a);
by
serial << "A:" << a;
