The page doesn't make what SPICE is for obvious, aside from linking to other pages, but they are not talking about the circuit simulation tool. (It appears to be some sort of tool for accessing desktops of virtual machines remotely.)
I have the impression that you could also use it for accessing desktops of real machines remotely, too, but that's only because I keep running into it when I'm looking for information about the real SPICE, a 50-year-old open-source program used to design every computer you've ever used and for which the IEEE awarded Donald Pedersen the Medal of Honor.
