Hey Bruce, this paper says many similar things! :D http://journal.frontiersin.org/article/10.3389/fncom.2014.00082/abstract
Thanks, that does look related and interesting (based on its abstract). I'll try to find time soon to read the paper and check out the related discussion it points to. There is also a Google+ community you are welcome to post it in, "collaborative design software", findable on my G+ page.
