Sounds like that would up the annual fee on your software, when you're also paying for those servers to be kept up and running.
I'd be more interested in an easier way of accessing your archicad key from multiple machines through internet when running a software license on network.
That way the hardware investments needed stays on your end and the 'cloud' solution is something you opt in on.
