Surely the applet just uses the same standard API that JOSM, T at H etc.
use and that the Rails port is backwards compatible with. If the applet
doesn't work with it, we need to fix it, not the applet.

I'd like it to be the obvious and natural way to use OSM. So port it to
Java as a JOSM plugin, or even porting it to ruby to be a function of
the rails server. Currently OSMfilter requires you to install a bunch od
dependencies, download a whole planet.osm, filter it as appropriate so
it will fit in RAM, etc. before you can use it.

Really there should be a way to just load the track into JOSM, have JOSM
download existing roads close to the track, (even if this means multiple
fetches to the API), and make the segments.

Which goes back to my JOSM can't hold much data problem.

Another thought is a method to perform the GPS filtering on the server,
and have the server be able to tell me where it has GPS traces that
haven't got segments yet - e.g. the ASTL data. This probably requires
some sort of spatial filtering, otherwise it will take forever.
