for location. An example use case is interim deployment of VoIP
emergency calls, before the device is upgraded to query a LIS via an LCP
itself. It will be common to use an IP address in this case.
The draft does not discuss the cautions we have long discussed when
using an IP address as an identifier. It's quite clear that an IP
address WILL be used for this case, and denying it is silly.
Considerations for its use should be provided. I think we want text
that discusses issues such as the effect of NAT and VPNs, perhaps a
discussion of needing return routability testing to assure the 3rd party
that it has a good IP address, etc.
Some of the latter considerations may also apply to other forms of
identity that may be used with this draft.
