I'm not sure that either technology is well-suited to the task that
you're laying out. You could (maybe) use NIDS to *detect* a user
mirroring a site -- if he was doing so at a high rate -- but this
would be more easily spotted in the web server logs.

You have a fundamental problem here: a user can slowly build up the
mirror, and since all the material is publicly available for them to
access, you need more specific criteria for the accesses you want to
prevent. What are you really trying to prevent? It's not just "making
a local mirror", it must be something slightly higher-level. Once you
know that, you can better decide what countermeasures you need to
take.
