I purchased and used an IP KMV back in like 2008 for the purpose of dealing with user computer issues at a remote site. This was prior to having ScreenConnect. Even back then I used iDRAC Enterprise for servers.
It was cheaper then TeamViewer, and let me actually reinstall the OS remotely. Since I had a Windows 7 USB stick on site also.
Today? ScreenConnect for everything, and I ship new systems. I would never use something like this today.
