For everyone who wants to have a dock, but with workspaces that behaves like they traditionally have (or if you just want to see how workspaces in unity should have been), try docky. It has a gconf option for showing only windows on the current workspace. I've been using it for a couple of years myself now and I'm very happy about it. Used to use classic gnome2 window panel, but I find this to work even better.
