"P2P users have found a creative way to fill up the more than 2 gigabytes of e-mail storage offered by Google's Gmail: file sharing. A new service created by Dutch student Robbie Groenewoudt taps into Gmail and creates an index of files that can be accessed by other users. Appropriately named G2G Exchange, the Web-based service does have some drawbacks. It requires users to hand over their Gmail account information, although it can be configured to index only e-mails with certain labels. G2G's FAQ page recommends that users create a new Gmail login specifically for sharing files."It was only a matter of time, but I wonder how Google will react to this if it becomes widespread? Google has gobs of money, which makes them a plump, juicy target for lawsuits.
