- How do you know that this client is a seeder?
- A seeding client may choose to send an incomplete bitfield and
fillup the missing parts with 'have' messages.
(Obscure workaround for ill-Traffic-Shaping or Seeding 'help')
- Verify that you are reading at the correct offset/data using
a network sniffer like 'wireshark' [1]
