[p2p-hackers] network coding put to practical p2p content dist. use

[Alen Peacock]

Bram Cohen makes some interesting arguments against such a scheme:
http://www.advogato.org/person/Bram/ (Nov 7 2004 entry, "erasure
codes").

I'm sure most p2p-hackers readers are familiar with this reasoning,
but I'm equally convinced that a lot of us don't necessarily agree
with Bram's stance, at least not in the general case.  At the same
time, I don't think anyone would argue that the costs associated with
using erasure codes inside a decentralized system (both in terms of
implementation and processing) aren't significant.
