No worries, I always try to assume that people are well intentioned with their questions until there's undeniable evidence otherwise!
I didn't have any specific ROI in mind, I just wanted to get the thoughts out of my head and onto "paper", and hopefully help out anyone who finds they have the same challenges. Also, if I'm re-inventing the wheel or missing other obvious ways of doing things, that would be interesting too.
Sorry it's not any deeper than that! :)
