Since mysql 4.0, their client libraries are under GPL not LGPL, which
means you're violating their license if your app is linked to the client
libraries.  Playing games with not distributing the server doesn't get
you out of that.  What you're doing is *exactly* what they want you to
buy a license for, and if they felt like coming after you I think they
could enforce it in court.
