I see this could be little more error-prone. And maybe little more
variable. I know we can add a variable for every test making use of some
sharemod persistence, but that would mean there will be big mess very
early. I would probably just do something like this for example:

data = {}

And then in the test when you want to use shared variable, you can do:

Setting:
sharedmod.data['my_test_variable'] = 'test_value'

Checking:
if sharedmod.data.has_key('my_test_valiable'):
    # The value is set

Getting:
sharemod.data.get('my_test_variable', 'test_variable_default_value')

But if the current suits you better, I think you can go with it as well.
