Nokia and Avvenu today announced that they have signed an agreement under which Nokia will acquire Avvenu.

Avvenu provides Internet services that allow anyone to use their mobile devices to securely access, use and share personal computer files, even if their host computer is turned off.
As part of the Avvenue Access 'n Share solution, Avvenu Music lets you remotely listen to music you have imported ("ripped") to your Apple iTunes library on your Windows PC for free. Using Avvenu Music, you can listen to your music using the web browser on any other Internet-connected Windows or Apple Macintosh personal computer.
I could imagine that you soon be able to listen to your iTunes library on a Nokia phone.

Founded in 2004, Avvenu is a privately-owned start up headquartered in Palo Alto, California. Avvenu will be integrated into Nokia's new Services & Software unit as a part of the company re-organization that will take effect on January 1, 2008.
