a couple of years ago tridge demonstrated things you can do with DMAPI interface and even delivered some non supported example code to demonstrate it :
https://www.samba.org/~tridge/hacksm/ keep in mind that the DMAPI interface has some severe limitations in terms of scaling, it can only run on one node and can have only one subscriber. we are working on a more scalable and supported solution to accomplish what is asks for (track operations, not just delete) , stay tuned in one of the next user group meetings where i will present (Germany and/or London).
