Sadly no :(
I've had the device on tcpdump for the last week and all it's doing is DHCP packets, Canonical/Ubuntu updates, and a bit of totally other plausible noise.
I'm also still poking around on its drive to see what it could have been set up to do. I'm still cautiously optimistic I'll find something (I actually have a second fresh device that I bought at the same time I might also poke at), but not sure when I'll have more data.
