Python Module with IPPOOL module

Hi there, I'm not sure if anybody has been able to do this, Haven't found much on the web for the Python with freeradius, but I'm trying to allocate a IP Pool to a specific set of users with a Python module. Now I know the Pool-Name is a check item and not a Reply Item, but can I do this from Python or is just not possible? The python handles my Auth, Acct, etc.. However I'm trying to drop different users into different IP-Pools depending on criteria in a database. So I'm unable to do this from users files and such... Any ideas? Thanks, Michael da Silva Pereira
