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 just started, and if you compare the number of people using Skype to the number using a telephone network around the world, we're still just starting.

They also can combine voice with instant messaging and online file sharing.

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.

Skype is for any individual who has a broadband Internet connection.

If you want to be an entrepreneur, it's not a job, it's a lifestyle. It defines you. Forget about vacations, about going home at 6 pm - last thing at night you'll send emails, first thing in the morning you'll read emails, and you'll wake up in the middle of the night. But it's hugely rewarding as you're fulfilling something for yourself.

We also have a conference call feature where up to five people can talk on one Skype call.
