I'm not sure if it is of any help, but with http://yournavigation.org
(which also uses OSM) you can specify which distance algorithm to use.
It uses this PHP class for the calculations:
https://github.com/treffynnon/Geographic-Calculations-in-PHP
Available methods:
Vincenty
Simplified great circle
Haversine
Cosine
Add a &v= parameter to the request to choose the algorithm:

/offtopic: I see YOURS should be upgraded with the new class...

Hi Gerd,
I have looked at your example file in QGIS and Global Mapper and they
show distance like JOSM. I don't know why there is so big difference. My
guess is that it could be caused by spherical versus ellipsoidal model
of the Earth. Maybe you could test algorithms based on Vincenty's
formulae? See for example:
