[Starlink] It's still the starlink latency...

I don't think we need quite that call to inaction :-) . I can certainly see
the problem on my Starlink connection, and can classify the degradation of
performance under load that should not be there. It's insufficient for a
low latency video call, which I think is an easy definition of a
lowest-common-denominator for anything involving vehicle control.

My ham application is equivalent to a low-latency voice-only WebRTC call.
There are diagnostics for them, and for the video call mentioned above. I
would hope that Taht could put together numbers.

This does seem to be a call to inaction, doesn't it? Dave and Co. have been
working on WiFi for quite some time and have good papers.
