Ok, here is an updated and fixed example using auto release pools and proper server retirement protocol. I also extended the server to be able to publish a passed in texture. Technically speaking it should not need its own internal ofTexture but having a one-shot publishScreen function is kind of nice. I think it could use a bit of cleaning up, but all in all its pretty nice and works exactly as the QC implementation does, which is nice.
Here is a link to the updated XCode Project.
