This is awesome! Thanks so much for all the questions and suggestions.
I am already interviewing locals, for example, a local (Peruvian) Dakar volunteer who goes out into the desert and reports back to ASO telling them which sections are impassable/dangerous/extra difficult. He doesn't get anything in return, not even bivouac access, yet he does it anyway every year. I'm going to tag along and see the process up close!:)
I haven't yet figured out the best platforms, especially for live videos, plus the WiFi will probably be spotty, but I'll do my best.
