My previous job actually stored the output of a crashinfo-like script for each panic into a database along with metadata such as a one-line summary (it even had some limited ability to auto-tag known panics). However, it required a good chunk of time *every* day to check new panics received each day to see if any were not previously seen before, or new variants on an old panic, etc. The time was non-trivial and I do not think would scale well to the all-FreeBSD-users universe. -- John Baldwin
