The idea of putting their probes (or even anchors) next to Tor relays and/or OONI probes seems an immensely good idea because doing this will yoke the interests of generic network infrastructure people with those of Tor and OONI.

I'd be happy to bring them to the Tor meeting in Berlin, but they seem a better fit for the OONI meeting in Italy.  So I'm inclined to have you invite them.  Their community contacts are:

Tell them to bring extra probes/anchors to give out to OONI attendees.

If for whatever reason they can't come to the Italy meeting I'll invite them to the Berlin meeting.  Not as good a fit, but better than nothing.
