	This is why I see it as a non-issue, the data is broadcasted and
nobody is compelled to utilize the IETF network or bring an electronic
device to attend the meeting.

	By having a device set to join the IETF network it seems
that opting-in to share your data has occured.  Some people may want
a form of explicit consent or other details, but I've been to this
rodeo before and expect people to snoop on me in a public forum
and take this into account.

	It's super easy to ID people regardless by DNS or VPN
type traffic.  Someone connecting to via SSH is
going to be a short list.  Same goes for hitting up $employer VPN
endpoint/allocated IP space.
