This is the only missing feature in ScreenConnect for us. It will likely not stop us from purchasing the software, as your company is very professional and the product is top-notch, but we do a lot of remote training of technicians, and it would be great if a second session could just view the first session in a read-only manner for training purposes. As it is, we'll have to use a combination of ScreenConnect and a low-cost VNC solution for training. Obviously, this won't make us look too professional to our customers.
So, consider this our vote for adding this feature in the future. It would seem to not be too difficult to offer a read-only viewer of another session, but we're likely over-simplifying it.
Thanks!
