+I think it is useful to question WHY particular files should be securely deleted.
+
+For disposing of a disk, something like DBAN would be an excellent tool.  (WIPE 
+seems a little dated, since a lot of disk technology has changed since 2004.)
+
+For individual files, if the particular file should really be securely disposed 
+of, then maybe training the users disposing of such files to use srm could be a 
+useful approach.  (There would likely be no point in securely deleting most files.)
+
+Then there is always the option of an administrator using srm on items in the 
+trash folders on a regular basis.  This could be done automatically by a shell 
+script, if desired.
+
+A utility that periodically sanitizes free space could be useful, as well.
+
+Changes in the filesystem or the kernel seems the only reliable way to ensure 
+consistantly securely deleting all (or all of a defined subset of) files.
