@evan: That's what I'm doing currently - serializing and writing the

instead of three.
Well, the checksum must be a separate "message" from the content,
since you need the content bytes in order to compute the checksum. At
least with the "official" implementation. But you could use the
content message for the "magic" bytes part.
I would just use a CodedOutputStream/CodedInputStream directly to do
this, with something like the following:
CodedOutputStream out = ...;
ByteString msgBytes = msg.toByteString();
byte[] checksum = computeChecksum(msgBytes);
out.writeRawBytes(magicBytes);
out.writeRawBytes(checksum);
out.writeBytesNoTag(msgBytes);
