integer only GPS navigation object

I have been working in my free time on a small object for integer only navigation.
It is a spin only (I plan to test a spinLMM version to speed up a little bit some functions).
Being integer only is quite fast, and it uses cartesian planar projection. In the past I started also a page on http://propeller.wikispaces.com/ with the basic assumptions behind.
It works well as long as distance to way point is limited (it depend on you, but few hundreds of miles are still acceptable) and you are not navigating near pole (if you need such a function and an on site testing let me know...).
Anyway the object does its work, and is quite reliable.
I would like to have your opinion, and in case post it to the obex.
The demo uses string from the DAT section and not from a GPS, but it is made to process NMEA strings from GPS_IO_mini or similar.
