Why not just use Autz-Type? We may need to make a few identical autztype
sections with only the pool module changing but that will be more general.

It was intentionaly ommited.
First of all, there is a certain period in every day (21:00-04:00) where the
modems get crowded and usually are used in their full capacity. In such a case
checkrad checking will just kill performance without helping us have an adequate
number of free ips.
Also, if we end up not having a free ip to allocate to a user then we most
probably should enlarge the ip poll or/and the timeout/retry count
parameters in the access servers for accounting. Otherwise we are just treating
the symptom. We should never lose an accounting packet. In my installation we
lose 5-10 out of 20000 accounting packets. In my opinion tracking
accounting-stop and access-request packets is more than adequate to maintain the
ip address pool.
