Changing MXD to store relative pathnames to data sources via ArcPy

Question

Just wondering if there is way via ArcPy to change an MXD to store relative pathnames to data sources. I would like to run  a Python script that loops through multiple MXDs in a given folder and changes them to relatives pathnames.
Thanks
Roberto

if this helps. 
10.1 SP1import arcpy, os

#workspace to search for MXDs
Workspace = r"C:\Geo"
arcpy.env.workspace = Workspace

#list map documents in folder
mxdList = arcpy.ListFiles("*.mxd")

#set relative path setting for each MXD in list.
for file in mxdList:
    #set map document to change
    filePath = os.path.join(Workspace, file)
    mxd = arcpy.mapping.MapDocument(filePath)
    #set relative paths property
    mxd.relativePaths = True
    #save map doucment change
    mxd.save()

Might we be able to write to this property in future releases of ArcGIS? I've heard the ArcPy Site Package may be expanded in 10.1+.

Not in 10.0. The MapDocument class has a relativePaths attribute, but it is read-only.
