As part of some research toward my degree I am conducting a survey of P2P users. The survey takes only a few minutes to complete, so if you have a little free time I would really value your response!
The survey is up at http://www.p2psurvey.com. I've tried to answer the common questions on the front page... if you want to know anything else you can mail me, or reply to this thread
You also get the chance to win some Amazon vouchers when you complete the survey!
