A friend of mine sent me this as well when I told him about it. My
main concern with Bitmessage is the size and complexity of the
protocol. My protocol is just a struct:

struct dinet_packet {
    uint8_t id[16]; // prefix + random in the default client
    uint8_t data[1024];
    uint8_t checksum[32]; // SHA-256 checksum of the previous two
fields, to avoid flooding the network with duplicate packets
};

Should be easier to analyze and study, I would think.
