Sounds like a valuable service to me. You have my (modest) vote. A few questions (and I don't really view this as critical, just curious) in order for this to be sustainable, you'd need to drastically expand your pool of participants, right? Have you done any calculations on the number of participants you'd need to operate sustainably without the DHF? What would it look like with different levels of fees charged? When would you personally consider the project financially successful? What is your target userbase/income?
