Idea:
We already use Bitmessage for sending message.
Let's fork the code and turn Bitmessage into a browser - Bitbrowser.
Users can upload HTML+CSS+JS and the files will be hosted in the swarm, bittorrent style.
As long as a website is popular there will be seeders.
Namecoin or a similar technology or derivate thereof replaces DNS.
How to get started?
