Wow, I go away for a few days and there's a flurry about my post! How cool! Discussion is how we figure out what works best!
The only "plus side" to the RealVNC tools, that I could see, was that you could use them on multiple platforms. I agree with the others that the Remote Desktop, or PCAnywhere type choices may work better (or free), I just hadn't found anything that would span so many OS types. Not a perfect solution, but "A" solution.
