Rob,

There isn't any canned approach to this in OGR.  You could write a
customized version of ogr2ogr that applies your transformation likely
using the GDALGCPTransformer for mapping between your local coordinate
system and a projected coordinate system.  In theory you could also
implement a python script to do this, but then you would be on your own
to do the actual transformation calculation.  If you wanted to take that
approach you could look at:
