For this particular application, venti and vac are overkill.

md5=3D`{md5sum <$file}
mkdir -p `{echo $md5 | sed 's!(...)(...)!\1/\2!'}
mv $file `{echo $md5 | sed 's!(...)(...)(.*)!\1/\2/&'}

Also, for the particular motivation of rejecting viruses,
I've been very happy with /mail/lib/validateattachment
(called by upas/vf).  I haven't gotten a virus via Plan 9
in months, and I used to get a handful every day.
