Ever since we built enough nuclear ICBMs to threaten mutually assured destruction, the most important military personnel have been those who diligently guard their country's nuclear weapons arsenal . As long as we possess nuclear weapons, their job performance (or lack thereof) may one day save or destroy millions or billions of lives. Like the Night's Watch in GoT, being a nuclear officer is not a glamorous job, but this work is infinitely more important to the safety of regular citizens than any other section of the armed forces or law enforcement (obviously TSA would be near the opposite end of the spectrum of usefulness). Its time we reassess our definition of heroism around the people that really make the difference in our continued survival.

I use LogMeIn free and teamviewer. With all remote support tools, you have to get the user on the remote PC to activate/setup the remote connection, and in this area Teamviewer is faster and easier. Like Logmein it plays well with Windows Vista and 7's User Account Control, and like Logmein you can do Windows -> Mac remote control and the reverse. Unlike LogmeIn Free, Teamviewer enables file transfers (with low overhead). Finally neither require any router/port forwarding configuration, building a custom executable, etc. Remember one of the most important criteria for a remote support tool is ease of setup for the person being helped.
