You might find the 3rd party module 'shove' is more suitable for your
needs here.

http://pypi.python.org/pypi/shove

It provides a lot more backend support than shelve, of particular
interest to you would be filesystem (& maybe sqlite).

>>> from shove import Shove
>>> fsdb = Shove('file://persistent.db')
>>> fsdb['key1'] = 'value1'
>>> fsdb.close()

In this example, using the file protocol will produce a
'persistent.db' folder with the key/value pairs stored within it as
files. This should be cross platform enough for your needs.
