Centralized Arpwatch?

[Russ Starr]

Is there program out there that can collect remote arpwatch logs and
keep a "running total?"  I have about 25 remote places that I would
like to put a minimal floppy or CD distro with arpwatch and maybe
remote syslog to a centralized server.  I'm sure I could whip out some
shell scripts and put all the known hosts in to a csv.

My ultimate goal is to be notified of new hosts on all our network
segments.  I'd probably take snapshots of the central csv and do diffs
with e-mail notifications on a regular interval or something similar.

I have also toyed with the idea of using arpsnmp to collect all remote
router's arp tables via SNMP and collect them in a similar manner.

Does anyone have any recommendations?  Maybe there is a better-fitting
alternative to accomplish this task?

Thanks,
