As for Layer, that’s getting verrry impressive release.
A bit too impressive in a way. With so many nice features and ability’s being given by one company doing an end-to-end service, its harder to argue the superiority of having a free-for-all distributed system like the internet itself is ;)
Still, great work by the Layer team!

Incidently, regarding my talk, I appolgise again for my connection going. Any extra questions, feel free to ask them to me direct, or post them on the wiki’s faq;
