To share desktops, I recommend using the free for private use, cross-platform app from teamviewer.com.
TeamViewer – the All-In-One Software for Remote Support and Online Meetings
Remote control any computer or Mac over the internet within seconds. I’ll send you an email invitation. When you click on the link provided, Teamviewer will download and install on your computer the software needed to share desktops, control the mouse and keyboard remotely, and have an online meeting
You can remote control the PC or Mac of your partner as if you were sitting right in front of it. New features such as VoIP, webcam and application selection will give you an even better, easier and faster desktop sharing experience.
It’s not the only option for sharing desktops. I also like to use Skype.com and http://uberconference.com/karenkreps.
