> maintenance: still necessary, hire anyone but probably the expensive guys from before

Don't forget: sometimes the copyright is still owned by the contractor that developed it, at which point the options are only "hire the expensive guys from before." Want to make a change and the vendor can't/won't? Oops, guess you're starting over from scratch! Or you don't make the change you wanted to and live with it as-is.
