a large part of the tech. has been discussed in RMRG (an IRTF group)
and the RMT WG of the IETF...its not terribly secret - there's some
cool FEC codes (see patents) plus some neat protocol work
the "set a fraction" and "share fairly with TCP" are choices, obviously, not
i think unicast use of layered FEC is quite a cool idea ...
