Doesn't pickle.loads just do what you need ? e.g.:

>>> pickled = file('test.dat', 'rb').read()
>>> obj = eval('pickle.loads(%r)'%pickled)
>>> obj
<__main__.MyClass instance at 0xb7bfb76c>
>>> obj.a, obj.b, obj.done
(1, 2, 1)
>>>

As I've never used the persistent_id mechanism of pickle I don't know
if that would do the trick.
