Comment Interwoven DMS (Score 1) 237
Depending on your budget, there may be some value in looking into the "Interwoven" Document Management System (DMS)..
Its primarily marketed to legal firms, however its got great file tracking (i.e. who, where, when opened, printed, viewed, and for how long.. etc..) and is quite well rounded to suite the needs of just about anyone.
Has no Linux suport for the server or desktop clients though...
