Cool. Traces do look better, but we're still not seeing video from niri. A
tcpdump shows no traffice at all from niri.

Stuart's getting some odd mtraces, he's going to send them along to ag-tech.

Oddly (perhaps), audio is getting through, with a lot of dropouts. Maybe
that's the melting router that bill posited, or bandwidth limits in place
somewhere?
