I just got off a webinar presented by the California Bar Association entitled: "Online Dispute Resolution: What It Is, How It's Done, and How to Craft a Contract Clause"
You can download it here, though I think it will cost $50.
It was hosted by the Business Law Section and the ADR Committee. We went through the eBay and SquareTrade ODR platforms in some detail, and then offered ODR clause language to be integrated into contracts.
