OSM and the OSM software stack is designed around crowd-sourcing, which 
an inch level accuracy requirement is incompatible with.
This level of accuracy requires expensive specialized equipment with 
specialized skills, and you can't use consumer or phone GPS units to 
record data.

Crowd-sourcing makes the technical design of OSM complicated, but here 
you'd gain that complexity without gaining its advantages. Additionally, 
a inch is near the maximum resolution of the API and many tools designed 
to consume OSM data.

I would recommend you re-evaluate your accuracy requirements to 
establish if they are truly necessary.

Because this isn't a question of humanitarian use of OSM, you might have 
more luck with a more general purpose mailing list than hot at .
