we're having some interesting results with this. In version 1.0.3 of the
SEA SDK (as opposed to just the runtime stuff), the strings 'all public'
and 'all private' are present in the mibiisa binary. It is possible to
read the entire mib using the 'all private' COI, however, we are having
difficulty using either 'private' or 'all private' to write values. This
includes when we have actually configured the SNMP daemon to use
private. =-)

On a system using 1.0.1 it is possible to use the 'all private' to kill
processes, kill connections, etc.... Interestingly, it is also possible
to use 'private' to change the system information. Again, as far as we
can tell, we are _not_ using private as a COI when we can change these
values.

We did not attempt any spoofing.
