I suggest we discuss this more either in #kclug or I could start a new channel
specifically for it...

In particular, we want to see what our planned features are (preferably
anything everyone suggests), priorities, and such before we actually start
coding. So this would be not just for developers and mappers, but for anyone
who would want to use it (which might not require a GPS-- I'd like to support
triangulation based on wireless AP signal strengths). :)

This warrants potentially seting up a formal list of it's own.
With consideration being given to the GPS enabled hardware that soon may be abandoned by Nextel as part of band reassignments. As for the AP strength concept- There are many RF sources-some like the new "HD Radio" that have embedded timebase data streams. Extraction and comparison is a non-trivial but possible position data source unless I am totally wrong in my understandang of how such things work. If HD radio has OSS hardware?

I humbly suggest a hybrid approach of the "passive" rf level and an "active" one of ping times. Yes, there ae many variables influencing ping times. The factors that make ping time correlation part of this kind of process are validating path viablity,sharing node granualarity informations, and overall matrix integrity potential. Bluntly put-each element that enhances accuracy and stability is a good thing. Potentially I suspect we could in microscale replicate DGPS style
correction data.
