RE: SLP reference architecture I-D

["EXT john.loughney@nokia.com" <john.loughney@nokia.com>]

Hi James, 
I have a couple of concerns about both your I-D's within the contexts and
current Status of this BoF: 

*	Each appears to be very Wireless specific (constant references to
GPS as the representative format for location) -- which this BoF hasn't
determined is the foundation for its objective in my opinion; We haven't
narrowed anything down yet -- if we're going to at all; 

*	Section 2.1 of (draft-nyckelgard-isl-arch-001.txt) doesn't seem to
allow for IP to resolve anything unless the Device is Stationary; 

*	These I-D's seem also to be very SIP-centric for Signaling Protocols
-- shouldn't this Spatial Protocol be independent of any other signaling
Protocols by nature? 

*	Both your "Security Considerations" section mention "The
communication between the various entities transporting location information
data MUST be secure" -- but don't explain if or how a PDA or Cell Phone will
establish a viable Security Association with 'the other device' with an
acceptable Cipher or key length? 

*	Both I-D's seem to indicate the user enters their device's location
in order to send that information to another device; I shouldn't trust this
method, should I? 

As a result of this -- I (as a Co-Chair) would prefer that
"draft-nyckelgard-isl-arch-001.txt" (or any other Individual Submission) not
be called the "Reference" or "Architecture" in the title until many more of
these issues be worked out. Agreed?

[<JAL> ] I'll present this draft.  I note all of your concerns, & will try
to take them into account in my presentation.  Let's talk in Adelaide about
what changes to the draft should be added before re-issuing the draft.  The
draft was done rather quickly (Sören and I were both completing other drafts
as well ...)  I do think that the title: ISL Architectural Considerations is
appropriate, but we should consider the above points as well.
 
best regards,
John
