For some more background/ideas that might be useful in this
conversation, just in case you haven't seen it, I highly recommend
reading:

source-software-study

I found this a fascinating paper and while it's over a year old now
and I personally question some of the conclusions, overall, it
remains excellent reading for participants in this thread.

Sincerely,

Carl
