Oh no, I'm being genuine. Documenting the process itself wasn't what I was curious about, I was wondering how you'd go about your last bullet. Accepting lots of currencies can be hard, but I guess I'm not super familiar with online escrow services. I'm not sure how simple they can make that process, or who would pay the cost of using them (I assume they're not free).
I was also wondering how automated or manual you would envision the review process. I'm guessing your hope would be that the small deposit would stem the flow of submissions enough to make it all possible to review manually again, and you would also manually return all the payments sent to escrow?
