To the best of my knowledge, its not the norm to attempt to resend missed packets in a multicast setup.

Because the Receivers are supposed to be hi-fidelity stuff, I thought I'd implement a redimentary "second bite at the apple approach" in tRio. And so if a packet is missed, space is left for it in the buffers, a resend request is sent and if it doesn't arrive in time for the decoder then that's just tough luck.

Normally this works fairly well, but if too many packets are lost, then things come off the rails.
