	I'm not saying there may be regulatory regimes where the legal
situation may be different than what I outlined above, but the easiest
way to not be part of this is to opt out by not using the IETF
network.  Seems like a fairly affirmative way.  It's interesting how
IETF went from being engineering based to lawyer based.

	The adage about how many people it takes to build something
vs tear it down seems like it may be applicable here and private
*constructive* input to the parties involved would have a positive
response.

	My experience is the people who gripe the loudest tend to be
ones that didn't investigate the device behaviors earlier.

	I've looked at traffic that my machines receive at these
networks as part of troubleshooting and a fair amount is revealed
in the DHCP request, including company names, usernames, etc..

	On a mac/apple device to help some of this leakge go into:

	1) itunes, set your library name to something generic like "my music"
	2) system preferences -> sharing -> computer name -> my computer
	3) messages -> preferences -> accounts -> bonjour and uncheck all
the boxes, including the share my IM contacts and e-mail addresses.

	for iPhone/iPad change your device name:

	settings -> general -> about -> Name

	If you are worried about your PII you likely would have already
done this, but if not, please consider the above steps.

	I'm sure there is a similar process for other applications, but this
is just what I have at my disposal for a quick write-up/response.
