So... it wouldn't be too hard to write a program that actually DOES "delete" the program... It could read the size of the prog/var/whatever, erase it's VAT entry, and start filling the space with nop's till it went the entire length of the program... (of course, there would be no way to recover the data after a deletion like that, but that's the point.)
