I have ZERO idea of the technicals, but is the main problem storage?

If so, would it be reasonable to assume that there are several tiers of notes in terms of cost, like text-only (short), text-only (long), static images (however you classify them, if you do), audio, video, streaming...

... and in that case, would it be reasonable to have different specialized relays, or payment tiers, depending on what you want to post?

At the same time, how much of this storage can be just passed on to the users' devices? I would say, if you want permanent storage of your shit, you store it on your device.
