Is shelve in SciPy based on the shelve module in the standard Python
library?  If so, it uses pickle to store its data, and there should be
little difference. But since that doesn't seem to be the case, perhaps
you could look for helper functions for SciPy's shelve, possibily in
combination with cStringIO, to store the data using a StringCol and
restore it when the data is retrieved.
