It's hard to imagine that we can avoid this if we are in fact going to use
H3 as a substrate.

I do think it would be useful to ensure the RIPT->RTP gateway can be
stateless and transparent (i.e., you can transform a RIPT frame into a RTP
packet with reasonable fidelity), so that said gateway is all you need in
order for existing services to participate in the RIPT ecosystem.
