The systems come close to but do not quite support the illusion of being at a remote location. In particular, a user is not immersed in the remote environment and cannot physically manipulate remote objects, which would be required, for instance, in remote surgery. This is the goal of the telepresence project at UNC, which will use a ``sea of cameras'' to dynamically create a remote environment as a virtual environment at the local site.
