Hmmm... I don't /think/ it's related to encryption as I'm running this
all on a local setup (clients, tracker, etc.). I created the Torrent and
specified no encryption and the various properties don't suggest
anything to that affect. I'll recreate with a plain text file to see if
I can spot the "watermark" when sniffing the data.
I'll look into the encryption stuff just to be sure.
