Chris,

that is the ultimate goal, yes. There's another goal of making it easy to interact with IDEs. At the moment, it is a M.S. project,
due to completion this spring, so not something immediately useful for production. At the same time, it's something potentially
rather big. So, no promises, but watch the progress there.
