If it's only traffic on 44net, I would argue there is no expectation of privacy to begin with, since it's only supposed to be Amateur Radio related traffic.
It may even be a deterrent from people who are just fishing for IPv4 address space and have nothing to do with the AMPRnet.
But, the "expectation of privacy" standard is very US specific, and this is a global allocation. Perhaps erring on the side of caution and only providing aggregate data is best.

The flow data records source and destination address and ports, how much traffic was transferred, the time of day, and how long the connection lasted. Every flow record is about 50 bytes of data, and there can easily be a hundred of them per second. In aggregate, it's a lot of data.
And it has privacy implications.
I was originally considering making an interactive netflow inquiry tool available on the gateways section of the gw.ampr.org website so gateway operators could see what traffic their AMPRNet router is handling. But because there's no way to restrict it so that someone could only view flows involving their own endpoint or subnet, I think it's too much information to be made freely available for people to browse. And there is the consideration that inquiries could wind up presenting a significant load on the system.
I think that presenting anonymized aggregate data wouldn't be a problem, so I'm going to look into that. Probably some traffic density graphs would be ok. And I'm willing, once the tools are installed and working, to make extracts of the data for a gateway operator who is having a problem with his traffic flow.
What's people's opinion of this?
