I have been going back and listening to old skool Hanselminutes.com podcasts. Show#8 points out some free tools that may still be somewhat useful:

• TeamViewer
  TeamViewer connects to any PC or server around the world within a few seconds. You can remote control your partner’s PC as if you were sitting right in front of it.
• cr-documentor
  DXCore plugin for rendering real-time XML documentation comment previews.
