J, As I understand it, even the original creator cannot change the licence terms or revoke them. Therefore I'm unsure if they can give permission, since that would sort of be changing the licence.
All of Ron's CAD drawings "unless otherwise expressed" were made under CC BY-NC-ND 3.0 (as outlined in the header on ModelEnginenews.Org homepage) I think as Rod said, Ron's intentions were clear, and these drawings can be shared easily from individual to individual and will provide many years of fun for anyone with the passion and determination to follow them.
Maybe, you could host a list of volunteers who are offering to share the plans?
I have just been given (for free) a very modern colour laser printer that I'm hoping will be of high clarity so potentially I could also extend that to include hard copies printed on A4 for a transparent fee based purely on paper, toner, envelope and postage costs. The time and fuel spent driving about is my contribution.
