   I will try to find a spare time to some job in the area. I am planning
API like this (in terms of Python 2.x with anydbm):

# dbm.something module
import anydbm
anydbm.register('something', whichdb_test_function)

   whichdb_test_function is not required - whichdb module can provide
a generic test function:

def generic_test(filename, module_name):
    module = __import__(module_name)
    try:
        module.open(filename)
    except:
        return False
    else:
        return True

Oleg.
