wifi ip allocation

Hi every body, While all the documentation on the web seems to answer *NO*, and because I feel like i need to talk to someone today, I was wondering if there is any way to allocate IP address to wifi user using radius Attributes instead of DHCP? Or maybe I should ask... How can i allocate IP address from differents Pools based on login (final goal would be to have transparent squid treat user differently )? Thanks. -- Follow us on: twitter https://www.twitter.com/manainternet
