We don't need a twelfth system for encoding lat/lon tuples. Pick an existing one and start using it.

Currently, we have:

- decimal lat/lon

- d/m/s lat/lon

- UTM ( http://en.wikipedia.org/wiki/Universal_Transverse_Mercator_c... )

- MGRS ( http://en.wikipedia.org/wiki/Military_grid_reference_system )

- Geohash ( http://geohash.org/ )

- "Natural Area Code" ( http://en.wikipedia.org/wiki/Natural_Area_Code )

Please, suggesting something like this and encouraging people to implement it is like coming out with a device that only charges over micro-USB. Just... don't.
