I'm sorry, I can't find anywhere on the nLite site or in the EULA where it says schools can't use it and/or are considered commercial. Google can't find anything either. If it's not explicitly in the EULA (or website) then I don't believe you can make that insistence. Are schools legally defined as businesses or corporation in the (undefined?) country where nLite is developed? I strongly disagree with your "consideration". Businesses and corporations exist to make a profit, I can assure you these two schools would never be able to achieve that even if they tried. Everyone here - teachers, support staff, parents, and the community - puts in a lot of unpaid time and effort for these kids. We are a state-funded non-profit organisation. Nevertheless... May I politely suggest that you mention in a prominent place on the nlite website that schools cannot use this, or at least put the licensing rules in the site FAQ. Mentioning it in the EULA wouldn't go amiss either, infact I would think that the EULA might be a rather important place to mention it. Currently nLite is only partially deployed at one of these two schools I work at, it has only been so during the current month (Jan 2010) and its deployment is incomplete. I'll ensure it'll be off the affected school's images within a week (by Jan 29), and off all workstations within another week or two (by Feb 13). I will post a follow-up to confirm when this is done. A shame really, nLite is a fantastic piece of software.
