There are audit logs that you can turn on which will log every
ACL change.  Audit log output can be written to a pipe so that
a process can scan then in real time.  You can then have that
process send e-mail, log warnings, or even alter the ACL if
necessary.

There will be a talk at the upcoming workshop describing how
a combination of dump scanning and audit stream parsing was
used to enforce export compliance regulations.
