International markets are much bigger than the U.S. In Sweden we have 9 million inhabitants, and if you're successful in Sweden, you're not successful - it's such a small market.

We have 2 million users in the U.S. and about 13 million worldwide in more than 200 countries. We're getting 80,000 new users each day. And more than half a million people are connected via Skype at any given moment.

You have 1 billion people using the Internet with 200 million of those now using broadband internet connections, so the Internet has become a powerful network. It can carry calls.

If you could utilize the resources of the end users' computers, you could do things much more efficiently.
