Yes I do.  It's EPSG:26986.  Got that from WKT_ADAM.TXT out of
http://www.remotesensing.org/geotiff/proj_list/Wkt_adam.zip
So:
  ogr2ogr -t_srs EPSG:4326 -s_srs EPSG:26986 -f "ESRI Shapefile" outputdir input_shapefile.shp
will go from NAD83/Massachussetts Mainland state plane system to WGS
84 lat/long.
I tried to do both the shpcs2cs command of my last email, and this
ogr2ogr command and got shapefiles with the same extents reported by
shpinfo.  So it's six of one, half a dozen of another.
Hope that helped.
