LogMeIn Pro runs an entire Rampage workflow remote. approx 5 PCs and 2 Macs. The best scenario is to control the Macs from a Mac because of the keyboard but I use an XP box also. You can also conect to multiple machines with just one remote box and use either tabs or dif. windows. The diff. windows works great on a multi monitor system, just like being there. They used to have a free version but I don't think so anymore, but I am sure it is much cheaper than any of the workflow add-ons.
