I just saw an interesting documentary about encryption. Part of it was about Sealand:

Wired.com
Hunkered down on a North Sea fortress, a crew of armed cypherpunks, amped-up networking geeks, and libertarian swashbucklers is seceding from the world to pursue a revolutionary idea: an offshore, fat-pipe data haven that answers to nobody.
By Simson Garfinkel
Ryan Lackey, a 21-year-old MIT dropout and self-taught crypto expert, sees fantastic things for himself in 2005. For starters, he'll be filthy rich. But his future is animated by more than just money - to wit, the exploration of a huge idea he thinks will change the world. Lackey's big concept? That freedom is the next killer app.
Before you get too choked up, you should know that Lackey means giving corporations and frisky individuals the "freedom" to store and move data without answering to anybody, including competitors, regulators, and lawyers. He's part of a crew of adventurers and cypherpunks that's working to transform a 60-year-old gunnery fort in the North Sea - an odd, quasi-independent outpost whose British owner calls it "the Principality of Sealand" - into something that could be possible only in the 21st century: a fat-pipe Internet server farm and global networking hub that combines the spicier elements of a Caribbean tax shelter, Cryptonomicon, and 007.
This is the company's website, and here is Sealand's official site.

Here's a pic of the 'country'.

Could this be the world's most secure, most anonymous hosting solution? Or is it just some punks making big bucks, supported by their self-claimed independency?
What if they sign a billion-dollar deal with some major company, then literally tell them to bugger off - the place has enough firepower to defend itself for a while...
Ryan Lackey: "We only comply to rules issued by the court of Sealand." Well doh... there is no court of Sealand.
