Why should the same user get a new ip? If you use 802.1x there is an
RADIUS server. And with help of some specific radius attribute you can
give one user whenever it connects the same IP! Ok hostapd doesn't
support it, but it is possible to implement such things. If the user
has the same IP its only a part of routing that his connections keep
opened!

At the moment its only for authentication and to get keys from the
radius server. But its possible to implement other things.
