I attempted to create a Wave variant with little success. The issue I had wasn't the use of XML and it's technologies like XMPP, but the fact that the strength of XML (tree-based DOM) was flatout ignored in the delta OT scheme. Combined with Javascript where I got to the point to where the only way I got it to work was recursively counting characters, recreating the demo in the IO conference video feels impossible. This doesn't include criticisms like the weight of the protocol. Adding one character required an almost 200 character XML document. For a system of small messages like comments here on HN, it would be more efficient just to send a serialized state every second or two.
