If they built the shapefile support library they have enough to build the
helper binary to do it themselves, but, yes.

The string I posted works for UTM. If you have "state plane" data it might
be in feet, I'd guess something like:
shpproj old new -i="init=nad83:() units=us-ft" -o=geographic 
would work, but () needs to be replaced with the number for the state
plane covering the data, which can be found in nad/nad.lst in the proj
distribution.
