read out symbology/class breaks in .lyr file

Question

Hello, 
I have a .lyr file and would like loop through symbology/class breaks (?).  What I mean is the part that defince show this color from values x-y etc... so that I can read them out into a report or file.  I was able to do this in vba in 9.3 But, I am trying to do the same in version 10 with python and can't seem to figure it out as I am new to python and arcobjects.  If anyone has any words of advice on how to do this it would be greatly appreciated.  Here is what I have so far:

import arcpy
mxd = arcpy.mapping.MapDocument("C:\Data\PhD\Teaching\ArcGISProgrammingWithPython\jdm.mxd")
for lyr in arcpy.mapping.ListLayers(mxd):
    x = lyr.name

Thanks,
Derek

These properties are read/write.  10.1 is available now in beta.  10.1 final is scheduled to be available sometime in Q2.

Jeffrey,

Thank you for info for new version, that seems to what I am looking for right now (i am not OP).  Do you know if it has writ support, meaning that I can provide break values and labels to use from script?  Also, do you know when it will be available?

Thanks,

This can't be done with Python at 10.0.  At 10.1 the arcpy.mapping API has been expanded to includes some renderers (e.g., Graduated Colors, Raster Classified, etc).  This will be possible for those renderers.  For example,
mxd = arcpy.mapping.MapDocument("current")
lyr = arcpy.mapping.ListLayers(mxd, "MyRasterLyr")
if lyr.symbologyType == "RASTER_CLASSIFIED":
  print lyr.symbology.classBreakValues
  print lyr.symbology.classBreakLabels
