thanks -travis
As Issac has pointed out, you are missing the difference between threads and processes. A thread is similar to a process, but by definition threads share their memory space with all other threads of the same process. I don't know anything about openmosix, but as far as I can tell, it can only move processes, and even then, only processes that do not share memory (i.e. without clone_vm).
In MythTV, mythfrontend is a process. mythbackend is a process. All the different things that happen inside each of them are threads. You cannot separate threads across multiple machines, because they share memory space. There is no way to remove the shared memory from the threads, the entire design of thread locking and synchronization relies on shared memory. Since your hardware requirements mean both the frontend and backend _processes_ have to run on the same computer, you are out of luck. Openmosix could move the frontend process or the backend process to another computer if your hardware didn't require otherwise, but Myth already has this functionality with remote backends.
