Hey guys,
Sorry for the late reply. My response is that our licencing system isn't perfect. We've had requests for floating licences, personal licences, site licences, concurrent use licencing and more. We've decided to change how our licencing works. We haven't decided how exactly it's going to work yet - but trust us that we understand your qualms and we will be sorting it.
For now it works really well where you have one main render pc and two render slaves set up. If you want to do set-up work on your laptop, you can use the free version of Indigo for all your testing purposes, then use your main PC to start rendering the final.
Dale has done some amazing stuff with SketchUp recently, and we're constantly improving it. Indigo is the best quality unbiased renderer IMHO and on par with Maxwell for speed, I think learning SkIndigo is probably the best thing you could do to increase your ability to generate top-quality visualizations.
