Suppose you have a task: you need to connect to "machine A" from "machine B". "A" is behind the complicated firewall, so the only way is to ask someone to run the Server on "A" and use Listening Client on "B".
I would like to see this unattended at "A" side, like this: you instruct the Server "to try to add a client at IP=111.111.111.111 once per N minutes", get in the car, drive to "B" location and use (maybe, several times, logging off and on!) the "Listening Viewer" there.
I've actually solved this problem by using macro automation software (like AutoIt!) which repeatedly brings up "Add new Client" window, inputs IP, presses "OK", waits for "sorry, no chance" window, presses "OK" there and repeats - it looks really "perevert", but it works

Could this functionality be in RealVNC Server? I hope I am not the only one who'd appreciate this feature!
Thank you!
