Define what you mean by "integrating". We already provide content for Symantec's NAV.
If there's additional such content that you'd like to see, usually this needs to take the form of an Enhancement Request. Though as I'm unfamiliar with this particular product, what exactly does it do?
Reason I'm asking is that usually the following rule applies - "the more closely a product fits in with the patch/security solution we provide - the more likely we'll be able to provide content for it".
Vulscan has been written specifically with the capability to do "nearly everything" after all, so it's theoretically possible (if all you want is Content)?
So some more information here would be good.
