I chose and stuck with teamviewer for its cross platform simplicity. That, and not having to manage all the port forwarding across the 10 rigs i have in my little farm. Teamviewer lets me connect easily from my iphone, from which I do most of my work while I am away from home. I have been considering switching to linux, however my farm is 4500km away on the other side of the country, and I already burden my brother with enough hardware troubleshooting as it is!
