RE: [Geopriv] Location in SIP and "retransmission-allowed"

I would not think the aim of this work is to replace location-based
services with a protocol.

Telcos etc provide LBS but, at least in Australia, the user needs to
agree to be positioned. There are industry guidelines, the Privacy Act
and a Telecommunication Act to protect the rights of the users of LBS.
These are strictly adhered to by the LBS providers.

I realise that this group is here to protect geoprivacy, but to be
realistic this step is going too far. I sugest that GeoPriv keep to
your scope, and leave the LBS providers to differentiate and implement a
range of services any way they see fit within the letter of the law of
the country of origin. A protocol will not save souls from dubious
service providers - they just won't implement it.

Once you start expanding the scope, though, where do you draw the line?
  Can it be used to query a location-based rate computation system? Can
it be used to deliver location-targeted ads? Is the telco authorized to
do whatever it wants?

If you want to go that route, maybe we could define an
"allowed-services" element that the user could use to express that the
enclosed LI/LO could be used with particular protocols. LoST would be
the first example, RADIUS might be another, I'm sure more would come up.

  This could be a nice compliment to the identity-based rules in RFC

I hear that Verizon has claimed IPR on that. :)
