I don’t know if this would be a useful approach to you or not, but here’s my setup.
I run Cubase 7.0x off the dongle. However, I’ve also bought numerous pieces of Steinberg hardware (UR22/44, CMC controllers), and they come with a Cubase AI license. There are, of course, limitations on that version. However, one of my projects is a band with Cubase running at FOH. I find that the limitations of the AI version don’t conflict with my needs in that environment, so I run the AI version without the dongle in the live environment, and my 7.0x full version in the studio.
I’m particularly happy about this ability due to the chaotic and uncontrolled nature of bars and the risk of the dongle being broken through drunken carelessness, stolen, misplaced, etc. If that were to happen and I didn’t own a second license on a different dongle, the show would be screwed. Instead, I can run without that risk.
Perhaps something along these lines would be useful to you when you have to work from home. As an aside, I’m guessing you don’t own any plugins (e.g. Waves) that require an iLok, etc. Different Cubase versions wouldn’t help you there, of course.
