Fast routing? I don't think you understand how addresses work.
Imagine if we have addresses like email: user@domain.
It's not a problem for one host to have full list of "domains" and all list of routes. So, you will be able to find route from one domain to other, that will be extremely fast.
You don't need addresses like email addresses for that. You just need to have some sort of central authority that has a list of all open channels that would make it easier to route payments. The whole email addresses with domains just doesn't really make sense to me as to how that would be any better than normal addresses.
If you use something else, you will get slow network, like TOR or BitMessage.
I want extremely fast payment system, like a chat, not like BitMessage.
That's all I want to say.
Neither of those things are comparable. All of those systems (tor, bitmessage, and ln) use completely different protocols, you cannot compare them.
