So download it. Assuming it doesn't require special privileges, you
should be able to run it out of your own account.
Anyway, what you probably should do is overwrite each file in the
hierarchy with as many bytes from /dev/random as there were in the
original file. In traditional filesystems, overwriting a file reuses
its disk blocks. This should be good enough for non-military-level
I think it should be easy to write a perl script that accomplishes this.
