Really? I would have thought that it would take to much hub resources
to do that. Do you really think that it's feasible?

If I'm not incorrect, none of the things it will detect are very prone
to misconfiguration. Connecting to a user won't be affected by many
(or any?) factors that I can think of. Likewise, fakeshared files
don't have any apparent misconfiguration factors that I can think of

In any case, though, to avoid that users would increase a hubs load by
misusing it, I was thinking that, if the hub investigates a warning
and detects it to be bogus, it could ignore further warnings from that
same client for five minutes or so.
