If you really want the data shredded I'd think you'll likely need to work
at the fs level for journalled filesystems.

Maybe there's a reiserfs module for shredding deleted data?

Don't forget all the places the data might be such as in the network
stack, in memory, etc.

Any that do shredding upon delete?
