I found some cool software that will allow remote connections to other computers that's extremely easy to use - you simply launch an executable (no install of software required), exchange security credentials and you're in, connected to their desktop as if you were there. I've used other remote software before, but the ones I've dealt with (gotomypc, radmin, etc) have, at the very least, some setup and firewall/router configuration issues. So, this is great even for the absolute computer novice.

I really think it could come in handy for some of our support here, real-time tutorials (multiple users), exchanging files... the list goes on.
And the very best part - FREE!
