Stream Your Audio to Your Windows Phone With Didiom Pro

"Regardless of the desktop application that you play your digital music with, or how much storage capacity you have on your phone, Didiom Pro seamlessly scans your computer for audio files in the most popular formats, and maintains an encrypted channel between your computer and phone. What's more, when you add new audio files to your computer, Didiom Pro makes them available for wireless streaming and downloading to your phone in seconds."

Being able to access all my music and podcasts on my Windows phone is somewhat appealing, but I don't get grasp their business model - the app is sold on a 99 cent per month subscription, of $9.99 per year. If the desktop component of their app is installed on my system, transcoding the audio to 128 kbps, uploading the bits to my phone...why the subscription fee? There's typically a subscription fee for applications that involve a server-side component; some sort of Web-based storage or service. I've tried a few of these audio streaming programs in the past, and while they're fun to use, ultimately the battery drain from a constant data stream takes most of the fun out of them.
