The interpreter idea is somewhat interesting, especially if the "language" can be actually "compiled" into some threaded format or similar. I suspect that a number of special devices that you don't want to maintain a real kernel module for could be handled that way.
However, I also suspect that such a thing would eventually explode with special cases and support for new features people want, to the point where it gets quite complex, and a kernel module might be easier after all ;)
