Brain Fart
The internet itself is one big peer to peer network, so how come it is so difficult to make a p2p file sharing client without any support servers? Why don't software guys use URL host cache protocalls?

I downloaded an http server for free, and had it running off of my desktop. It was working fine, all I had to do was type in http my ip address and it would work. But then I found out that only I could access it; everyone else was blocked. Maybe my internet provider blocks it for security, but I wonder if all internet providers do so, or if there's some other way of getting around it. File sharing programs like Aimster and ICQ know the IP addresses of both parties, but the data transferred between the two doesn't pass through their servers. So I'm wondering how they link up the two parties, and if it can be done without them.

What are "URL host cache protocols"?

When you type in a URL your ISP checks it's host cache to find the corresponding IP address. Somewhere in the internet there is a system that links host caches across the entire net. However it works it's pretty effective and it doesn't use a central server.

I'd rather be sailing

This is some scary shit. You can look up a site and find the owner's address and phone number. I don't even want to post the site.

Thanks for the links Jack. I think if people looked into DNS protocalls they could build a very robust network without servers, or it'd be a good start anyway. This document was particularly informative: Keeping track of names and information: the domain system. If you could figure out to organize clients into different domains then a domain service could operate in the background to tell each node how to contact every other node.
