Moving Stuff Around

File sharing
Don't overload the sharer

Ephemeral Streams
Only exist for as long as something is being downloaded

BitTorrent and moving Blocks
Break up a file into pieces
Works faster by sharing the 'least popular' part of a file.

The Piece Tracker, Tit-for-Tat
Load-Balancing: share with me, I share with you

PDTP and the big picture of flows

StreamCast and FEC encoding
Avoids the need for a centralized piece tracker
Like a hologram for file contents

Streaming Video and Audio, MultiCast
Radio stations: data must arrive on time, in order.
