Steve, The main challenge for this solution is the definition of all audit events that imply removable media has been attached. Juraj's example of monitoring for mount system calls covers the edge case of copying to/from mounted devices (given you also identify removable devices mounted as opposed to say network mounts), but it would not cover the edge case of say dd'ing to a raw umounted device.
By the way, linking to http://people.redhat.com/sgrubb/audit/reactive/reactive-audit-thesis.pdf results in Forbidden You don't have permission to access /sgrubb/audit/reactive/reactive-audit-thesis.pdf on this server.
