Andrew, Ian, and Paul - thanks so much for the help. I need to study the code and I'll try to get a channel going between two Linux VMs. Latency and performance are critical (~500 MB/s), so I'll probably have more questions about best practices for large data buffers. However, once I have a working solution for Linux, I'll work with Paul (and the Windows PV developers) to use the current Windows PV interfaces to generate a solution between Windows Server 2012 and Linux.

If you need any assistance then please join the win-pv-devel mailing list and we can give you some pointers. There are already Windows kernel PV interfaces for many Xen features.
