As far as I understood the license the primarily is a very important. I had some discussion at work some time ago about Winsplit Revolution, which is licenced under CC:BY-NC-ND. They even have a statement in the Winsplit FAQ: Can I use WinSplit at work ? Of course you can ! The actual licence's "non-commercial" term just means that you can't directly make benefits with WinSplit Revolution. For example, you can't include it in a commercial package of software that you would sell. But as it is a freeware, you can distibute it freely as often as you want. The primary goal of using Winsplit is 'helping us make money' (by helping us do our jobs easier), which only slightly differs from 'making us money'. The only way it could (primarily) make us money would be if we sold it or if we would put a download-page up only to collect ad-revenue.
