Will check out Whitenoise. Saw it shared around but haven't tested it yet.
I like the relay model and from my experience with it, it has worked best. Flotilla being the prime example.
The accessability issue though is a problem as that is a serious barrier to entry. Wven for the motivated there is cost (cloud host vs run your own hardward) and technical learning involved. I'd like to assume anyone that has been on nostr for a while is motivated and commited to this protocol but I'm not sure how the cost and technical barrier scales to that user. And we should have that user in mind when building nostr. Religous/non-profit boards, social activist groups/organizers, the coveted "influencer" communities - these will expect both privacy and trus. These are the users I'm thinking of and we need low cost and low technical entry for this to scale to bring them.
