I was reading this website,

And I read about a point-to-point link that kind of confused me...

Ok the way I understand it right now is that there's a way that I can setup a computer in Florida and set one up in Washington, and I can buy a "point-to-point" link from AT&T or whoever that would connect those to servers, and it would work much faster than if those servers were simply hooked up to the Internet via high speed lines?

Am I correct?

If I am, would the following be valid as well:

If I wanted to make a massive multiplayer online game in such way that the entire world would be able to play on the same server, but in order to keep players' latency down, could I do the following:

set up one "Master" server say in the middle of US. Set up point-to-point links in all 4 corners of the US that would all conect to the master server. Set up point-to-point links from Europe and maybe other continents to the master server....

When a player connects to the game, instead of connecting to the "master server", he would connect to the closest "proxy" server instead and play through it.

If my previous assumption is correct, does it mean I could have players from all over US and the rest of the world playing on the same server through those "point-to-point" proxies, with low pings like below 100?

Point to point works well but using it to "shorten" an INTERNET connection would do little good. Most of the delay in an INTERNET connection is in the first/last few hops to a site. Once you get to the main connections distance becomes almost irrelevant.
