[OHM] tagging unit movements

[Rob Warren]

Richard,

The way I see it, we have two solutions:

a) Abuse the GPS trace storage of the base OSM database to store the  
movements and modify the  renderers to read them.
b) Implement movement through the use of multiple ways / relations,  
one for each time stamped movement.

I'm tempted to use b) for troops movements and b) for "born digital"  
material like AIS / GPS / radar tracks.

Are you planning to encode units as 'fronts' or as point data with  
nato-style unit icons?
