I need a tool which allows to take controll of user keyboard and/or mouse with support of Linux client (preferably on FLOSS license). It should ask the user about permission (I don't want to give a free troyan crackers). The NAT is not a problem - I have VPN. It should be able to work with lower resolution on client.
Windows is Vista (both 32 and 64 bit editions).
Does anyone know such client?
(By client I mean the connecting computer and by server I mean the Windows machine).
