Can we do any kind of distributed system without crypto? We can't trust crypto...
Perhaps probabilistically...
Want to be able to put data in, have it distributed, and be able to get it out on some other machine.
Availability: "distribute the crap out of it", doesn't need crypto.
Integrity: hashing, but we assume hashes can be forged. If we want to know that we got the same file, then simply send each other the file and compare.
