First, the website would only be meant for users without the app, so local hosting would not work. Second, it can only be read-only, unless you upload your private key.

I think it would provide a window into the social network, kind of "Oscar is using this, join him now by downloading the app!"

The implication I see is privacy of people clicking a user link, but the problem already exists now.

There's no reason a third party couldn't host a read-only view into Nightweb, performing something similar to tor2web.org.

The third party would be running their own Nightweb client, then visitors to the website would trigger content downloads on the client, rendered out as a webpage.

This would provide the "public view" without sacrificing the decentralized nature.

Great idea.

In fact, this type of functionality is hopefuly becoming an Internet Standard: http://www.internetsociety.org/articles/moving-toward-censor...

However, Bittorrent is not up to the task, due to NAT issues. UDP NAT puncturing is not present in this stack, right? Thus how is it going through carrier-grade NATs which block all these smartphones?
