One of the highlights of Kevin Lynch's Keynote speech at last year's MAX in Las Vegas was the eBay Apollo application. Code named San Dimas and built by the folk at effectiveUI it's a desktop application from eBay that allows you to manage your bids on eBay via the Apollo cross-operating system system runtime.
In a cleaver right to be the first San Dimas beta tester is now up for auction on eBay with the proceeds going to charity. The successfully bidder will also receive a certificate and a T-shirt. The auction item can be found at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=110131261193
If you're a little more patient you can apply for the beta at the Project San Dimas site: http://www.projectsandimas.com/
