I've become REALLY good at remote tools since I've been doing this remote thing (even before). I've used NetMeeting, Remote Assistance, GoToMeeting, VNC, CoPilot.com, LiveMeeting, Hamachi and a dozen things in-between.
Nothing has come close to the ease of Microsoft SharedView. It isn't heavyweight like LiveMeeting or fuzzy like VNC, plus it lets you show your screen to up to 15 other people.
One of the coolest things is that everyone gets their own "personal mouse pointer" with their name hanging off it, so you can see what someone is referring to when they are talking!
Today when I was at life's lowest ebb, I called Rob and Phil and said "guys, I need a code review." I did a Vonage conference call and they logged into the Shared Session using just my email address. Bam. No pausing, no firewall futzing, it's the greatest thing since FolderShare.
