There are wireless IDS/IPS products available that monitor not only the
airspace, but the wire as well. Many of these products will also actively
defend the airspace. Search for "wIDS" and/or "wIPS". Often the cost of
purchasing and deploying these products is more expensive than the cost of
implementing simple 802.1x port authentication though.

If nothing else, set up guest wireless piped to a cheap broadband
connection and create and/or enforce proper acceptable use policies on your
LAN. The less you fight your users, the easier your job is.

Of course all of this is dependent on the business and legal jurisdiction
you are in.
