Decoding Blob Object in Microsoft Access Database personal Geodatabase

Anyone broken the decoding on the text object for ESRI Geodatabases?  I'd
like to support the programmer that wishes to tackle the job.

Here is a Sample of a Road Name table in the Geo database

OBJECTID        SHAPE   FeatureID       ZOrder  AnnotationClassID       Element SHAPE_Length
SHAPE_Area      ROADNAME_       ROADNAME_ID     ANNOTATIONCLASSI
1               0       0                       397.72200370989 5202.26409780489        1       1       0

The road name it self if a  labeled as a long binary object.  If you export
to a shape file, its all blank.  I need the label to have its elemental
information something like x_position, y_position, rotational angle, text.

Thoughts, successes?  I'm hoping not to have to buy map objects and prefer
using perl/php to decode it rather then going to visual basic with map
objects which would surely have the answer embedded in their.  If someone
needs to see a sample data set, I have it available.

Thanks
