As of a few weeks ago I am no longer involved with OpenPacket.org. One of the reasons is a great new online packet repository sponsored and run by Mu Dynamics called Pcapr. I've had an account there for a few months, but it looks like the site is now open to the general public. Check it out -- there's a lot of cool features already.
