Re: Residential VSAT experiences?

I too have had customers in a previous life where the 500ms delay
really didn't cause any big issue.

Same with SSH and even heavier stuff like SMB.  Sure, it was slower
than expected, but I could still saturate the pipe pretty good.

Thing is...the kind of setups where you're getting 500ms delay with
little jitter is stupidly expensive.  Those are generally going to be
an SCPC (single carrier per channel) uplink with hopefully something
like IP over DVB providing a large pool of downlink bandwidth.  Expect
to pay over 4k per Megahertz (roughly translated to 1 Mbps
unidirectional depending your link budgets) of bandwidth (sometimes
substantially more, depending on what bird and provider you're using).

O3B looks really interesting.  I'm not aware of what they're current
state of deployment is, but they've got a MEO (I think) constellation
planned which will help a lot of with that latency.  Viasat had
something that looked promising too.

I mean..if you're looking at doing sysadmin type stuff where you're
already going to be pulling out your hair at times, doing so over
hughesnet is going to suuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuck.
