Incentivising a distributed app-server network to host content is a good idea. Presumably there would be different types of app servers? e.g. Text content, audio content, video content, images.

It would be great if there were some way for people to host content from their own computers when they are on - behind residential IP addresses - rather than requiring a server with a static IP. For scalability and speed, it'd be best if the content were distributed widely around the world so it's physically closer to the user viewing the content.
