RVC 0.91

Remote Viewport Console (RVC) is a free utility to view (and only view) the
screen of a remote computer across the internet.
It can compress the image as a JPEG or PNG and scale down the screen on the
server end before sending to conserve bandwidth.
It can also listen on any port via the command line,
auto send any given number of frames per second, or wait for a
mouse click before grabbing a frame.
It requires no installation, just put rvs.exe+pthreadvse.dll on the server,
and rvc.exe+pthreadvse.dll on the client and run them. It even works thru Citrix!
