Jump is excellent, BTW.
The article seems confused though. They say they are confused if Macs are being used to edit the show, but since the editors are remoting from one Mac to another it seems unambiguous.
The flavor of both the local machine and remote machine makes a difference. The OS of the machine you're remoting to makes the biggest difference, but since different OS's have their own ways of handling input devices, the local machine's OS is significant too. Every combo has its quirks, but I find Mac to Mac over Jump to be good.
