This works when the modem is on, and when you don't have a large
number of modems...  For a large number of modems, running that number
of smtpgets when there is an active problem to be solved is not fun.

How would you do historical data?

Remember what I said about caching and updating the cache?

(there should be a clue here for you -- this question always keeps
coming back to the very same answer!)

 How frequently would you poll the
CPE to put together your history?

I wouldn't ever poll the CPE.  All I ever need to know about CPE devices
is in my dhcpd.leases file (and the dhcpd syslog entries).

Greg, with all due respect, I have been doing all of this for longer
than you :) Back around 1986, I realized that there are no original
ideas in an Internetworked world.  Given the same problem, people tend
to come up with the same solutions.  Especially since nanog readers
tend to share the same paradigms...

You think so, do you?  :-)
