would it be possible to code an browser independent client-side server within the browser. I looked for an javascript solution but its not possible to open a socket. Is it possible with other standards or “reuse” the browser-socket? I am looking for a way to load content from another website – but there is always this “same domain-only”-policy.
There are a few p2p-social networks – how do they work?
Quick and dirty: Is it possible to load data from a different domain without a proxy to preserve the users ip/host-identification?
Here are a few leads on technologies that might help from the server side:
http://en.wikipedia.org/wiki/Push_technology#Long_polling
In particular, long-polling allows you to keep a continuous connection to the server to relay information.
You might also want to look into HTML5 WebSockets.
Using these technologies, you could set something up like a list of servers that can relay client updates to the network.
