Hey guys... thanks for all of the advice. I'm still trying to bang thru this...
I've read msdn articles until I finally understand why Windows has so many
problems: it's too darn complex. Anyway, here's where I'm at. Just
experimenting. Please chip in and help me make sense of this:

import win32net, win32security, pywintypes

shares = win32net.NetShareEnum(None, 502)
for share in shares[0]:
    try:
        sd = share['security_descriptor']
        print sd.GetLength()
        print sd.IsValid()
        print type(sd)
        text =
win32security.ConvertSecurityDescriptorToStringSecurityDescriptor(sd,
win32security.SDDL_REVISION_1,                                                 
                               win32security.OWNER_SECURITY_INFORMATION)
        print text
        bytes = buffer(sd)
        print bytes, type(bytes), len(bytes)
    except Exception, e:
        print e
