The entire netsync transport stream (after initial handshake) is
cryptographically MAC'ed.
I don't know how much integrity checking SQLite does on its own;
monotone, however, has SHA1s of everything interesting and the "load
from database" code always verifies these SHA1s before passing the
data off to the rest of the program.
