you could add support for the +s attr. zero-out current contents on delete.
it's sloppy, but like hans said, anyone serious about it should never let it
hit the disk unencrypted.

i'm the author of (one) wipe (aka ya-wipe, there's more than one "wipe") and
i made a point to be clear in the docs and on wipe.sf.net that encryption is
the only complete solution. my app is most useful for using on whole drives,
if you're going to sell it on ebay or something, and you want non-secret
personal stuff off (or at least invisible to almost all).
