Huh, I just wrote a similar tool for myself a few weeks ago. I use the sawfish windowmanager and have C-F7 set to cycle between emacs windows. I wrote some elisp to add a term ("my-workspace") to the titles of the windows in the current emacs invocations, and to tell sawfish's C-F7 to cycle between the emacs windows whose titles contain that term. Works quite well, and keeps my different projects entirely separate.
