P2P is perfect. Some sort of user voucher system would also be okay. Bounties can be nice, depending upon how they're structured.
Grants from OpenSats are more attractive as topping-up of project crowdfunding, over something like Geyserfund, rather than as individual grants (which are quickly devolving into employment contracts, which is the opposite of what I'd want).
What if there was something that paid for the infrastructure, like software, computers, hosting, etc? To alleviate some of the cost that came out of your pocket?
Then the grants are tied to expenditure, which is arguably worse.
I have no idea why OpenSats doesn't just contribute to crowdfunding, like other funds do. Everyone wants to know why we don't apply. Nobody asks why they expect us to apply.
This is a great question to ask the people on the panels and their approach.
