I am about to be moving and working remotely full time. Right now we use Yugma and Skype for developer conferencing and showing the desktop, but we do not pay for Yugma so there is no ability to grant control. Before I recommend anything that is not free, what are the best options for apps that allow you to share your desktop with multiple other people and also have the ability to grant control of your desktop.
I personally only need to worry about the software working on XP/Vista but feel free to put any options here, did a search and nothing came up about this particular topic so hopefully it can be a good place for everyone to come to.
