> what about having something reasonable for lag, like 30-60 seconds would that make a big difference or you think it would just eventually degrade too?

I think you would probably need something more in the neighbourhood of 10 minutes to really make a difference. If you could make a stable p2p live streaming app with the number of peers all watching the same stream in the hundreds and only 30 seconds latency, i'd consider that pretty amazing.

> Also do you think there's any way you can prioritize seeders in such a protocol? like some kind of algorithm that the more you share the more you're prioritized in getting the most up to date packets.

If we are talking about a livestream (and not "netflix" type streaming) then i don't think seeders are a thing. You can't seed a file that isn't finished being created yet.

If you mean more generally punishing free-riders, i think that is difficult in a live stream as generally data would be coming in from a different set of peers than the peers you are sending data out to, so its difficult (maybe not impossible) to know who is misbehaving.
