We've been doing exactly this for years.  Of course, we've been using
Sguil and not the time machine, but the idea is the same, and it's
quite effective.  As you mentioned, it's great for forensics, but it's
best when combined with an IDS.  It's pretty easy to validate most alerts
when you have the raw traffic to fall back on.

Nice to see another addition to the Network Security Monitoring arsenal!
