In the VRF case they can't: "This comes with a tradeoff of course and in this case is that you no longer can reach devices on the venue network, which shouldn't be a problem if you're only connected there for internet connectivity."
I also started my programming career thanks to Django, and I started using it while working at a local newspaper, so bonus points there! We built a system that our sales people could book ads, and then we could layout the newspaper through a canvas based tool (used Fabric.js for that), and then send the pages + ad stack to InDesign to be built. Was great to work with the whole process and Django was really never a limitation. I ended up moving on, but it'll always have a place in my heart.
> Taken a step further, customer support probably has the best understanding of their markets' needs!
People working in customer support, from my experience, sort of see the anti-survivorship bias working in action. Not many people call up to say how well something works. I would agree with you though on good Salespeople (ones that do try to understand what customers need and all that, not necessarily ones that sell the most) knowing what the customer wants/needs.
