Unfortunately, no: we can only stream Pandora to listeners within the United States.

Pandora has always believed strongly in honoring licensing and royalty guidelines as determined by the artists, labels and publishers. In the U.S. there is a federal statute called the Digital Millennium Copyright Act (DMCA) that provides a comprehensive license for streaming music via Pandora and similar services. At this time, there is no equivalent music licensing system outside the USA.
However, no matter where you are in the world, you can access non-music-streaming features of the site, such as music recommendations and artist information, by directly visiting http://www.pandora.com/backstage.

Also, if you visit the www.Pandora.com homepage, you may enter your email address to be notified if and when Pandora becomes available legally in your country.
