Questions regarding your talk at fOSSa2012

[snakeninny]

Hi,

I saw your slides this morning and have some questions at page http://barraq.github.io/fOSSa2012/slides.html#slide-16.

1. After Talker advertises to master and Listener subscribes to master, do they communicate directly via socket afterward, without notifying master?
2. Where does "scan" come from?
3. Can you gimme a detailed step by step explanation of this slide page?

Thanks,
