34 * - OR of matches is borked...
35 * - extend hash tables table as we go
36 * - accelerate looking for "all hostnames" and suchlike.
37 * - handle incomplete header
39 * - local deserializer
43 * - check LE/BE conversion for 8bit, 16bit, 32bit values
44 * - cryptographic hash
45 * - think about manipulations of header
46 * - implement audit gateway
