At first glance, it would seem peer-2-peer and file-sharing programs seem more about the controversially good service they provide than to profit making. And while Wall Street may not be paying attention, file-sharing is growing in new ways.

The new ASUS WL-700gE Wireless Storage Center provides 160GB of memory, allowing you to keep your BitTorrent downloads going even with your computer turned off. BitTorrent is a file-sharing system designed to distribute large files without a costly central server.

This expensive wireless router offers an interesting glimpse as to new ways software manufacturers will attract consumers. Even the 60GB and other large capacity MP3 players have an unspoken interest in the file-sharing crowd. Research company Ipsos Insight found that 19 percent of music on MP3 players came from illegal downloads, 6 percent from copying someone else’s CDs, and 44 percent from the person’s own CD collection. Only 25 percent came from download-to-own services.

And these numbers take some consideration, especially as downloading music legally proliferates. These high capacity MP3 players (and hard drives) allow users to download more music and movies then we logically have time to listen to or watch.

As a result, these products, in a sense, inspire more file-sharing (or just sharing of hard drives) to fill up all this space. Why spend the extra money for the 80GB iPod if you aren’t going to fill it up. That’s approximately 26,000 songs or 250 TV shows or 100 movies.

And anything you’re not watching, you can keep on your wireless router.
