This is exactly what the Lightning Console does. In addition, the console also 'knows' who owns the targeted systems and can send an alert to the effected end users when an IDS event targets a vulnerable server.

The big issue I have with VA/IDS correlation is the accuracy of the underlying VA database. If you are just scanning once a quarter or even once a month, this VA database can get out of date fast. Our approach is to use distributed scanning (multiple, tiered Nessus scanners) so you can scan a class B in hours. We also are BETA testing a passive vulnerability scanner which determines vulnerabilities and topology changes from watching network sessions.
