Grouper launched!

A cool new client based p2p, social network called Grouper has just launched. Founded by several of the Spinner.com folks. Congrats Josh! Check it out! Here's how they describe themselves:

Grouper is a new Windows based application that allows users to share their personal media within private groups. Grouper uses P2P technology connecting you directly to your friends' hard drives where you can share large files in a safe, encrypted environment. Grouper is a simple install and requires no firewall reconfiguration.
