Echelon is not a collection system, but an extensive filtering system.

The key component of Echelon is a computer function called 'dictionary,' which just does to text messages what (search engines) Yahoo or AltaVista do, it searches out words.

It's not just 1,500 servers, but a collection of 1,500 servers that act like a single computer system.

It's not just a filtering function.

The gallery is fantastic. It's beautiful with a great collection of unusual objects.

How extensive the problem is in India is still not known.
