Avvenu is a free service with optional premium features that lets business users and consumers securely access their office and home computers directly from a web-enabled mobile phone, PDA or computer – giving users secure remote access to all of their documents, music collections and images. The Guaranteed Access premium feature lets users access their important files even if their computer is offline or turned off. The My Media Play feature lets users play their MP3 and WMA music files from PC to PC, or from PC to any handheld device equipped with Windows Mobile 5.0. In addition to accessing their own content, Avvenu users can quickly and securely share access to their content with colleagues, friends and family. The recipients do not even need to be members of the Avvenu service in order to view the content shared with them. There are no limits on the size of images or files that can be shared.
