geeknik Servo looks interesting and I like the idea. However, may be early for production/paid software. I tried it on my Mac and it couldn't pass all BrowserBench tests. Then it was substantially slower than Orion on the ones it could do (e.g. JetStream2). Seems like it will need more time to bake before it is ready.
In an ideal world, Orion could virtualize the interface to the web engine such that either WebKit or Servo could be used and perhaps available as a platform/version build decision. However, not sure that would be like trying to develop an airframe that could accept both propeller and jet engines. In theory possible but the result not really good as either. Vlad et all know the architectures and issues best, but I could see why they decide to stick with WebKit for the forseeable versions.
