Re: Logging Scanner Jams (was: Audit trail improvement suggestions)

I think the statistical approach would be adequate, although the log with a
date and time stamp would be the preference.

I think that saving these for the 2.0 release is OK in the sense that we
might be able to "sell" the upgrade, vs having it be required.  However, it
might mean the AV would have to be recertified in many states.  Not good.
Other thoughts?
