That could work in some situations, but the problem is putting it in
the right spot to catch

i know they can log the payloads, so just depending on which segment i
want, i pick that IDS to watch.

Oops, I gave the wrong name of the vendor that sells that traffic
anomaly products (with Layer 7 inspection). Correct company is Mazu
Networks not Reconnex.
