I think people are talking about the pubgrid.
The pubgrid seems to be for not huge amounts of data, so I wonder if
others would run more serers. I am currently running 2, and 1 is full.
I fixed that by removing large shares and allowing a bit more space.
It would be nice to have more working servers (with reachable internet
addresses from client-only nodes behind NATS!), even if they only
offered a few GB each.
But we may need a config to disallow big shares, or implement accounting
on the pubgrid :-)
I've got a tcpdump of one of my servers that I can look at in my Copious
Spare Time; that may be interesting.
