TeamViewer lets you establish a connection to any PC or server within just a few seconds. You can remote control the PC 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. - TeamViewer enables you to do what you want without any hassle and without any worries. Private data, private conversations, and private meetings stay that way.
- Team Viewer requires installing a TeamViewer add on, but UltraVNC plays with whatever VNC server you have.
