I had a feeling you'd say something like that.  I know that at least some
RADIUS servers can support giving out IPs from a pool (probably even a
pool per radius client), but that just moves the problem from the access
servers to the RADIUS servers and makes routing more interesting.  Either
you end up with lots of /32's or you configure some summary-addresses on
the access-servers, at which point you may as well have assigned the pools
via local pool.
