take your pick ......and impliment/retro fit it/them internally ASAP into the current VLC multicasting codebase then, they have been around for a very long time now, its way past time something was done to bring the old MBONE (Multicasting backBONE)
tunnels etc back into current innovations, or are all the innovators no more.

3 Network Loss Characteristics
If it is desired to repair a media stream subject to packet loss, it
is useful to have some knowledge of the loss characteristics which
are likely to be encountered. A number of studies have been
conducted on the loss characteristics of the Mbone [2, 8, 21] and
although the results vary somewhat, the broad conclusion is clear:
in a large conference it is inevitable that some receivers will
experience packet loss. Packet traces taken by Handley [8] show a
session in which most receivers experience loss in the range 2-5%,
with a somewhat smaller number seeing significantly higher loss
rates. Other studies have presented broadly similar results.
It has also been shown that the vast majority of losses are of single
packets. Burst losses of two or more packets are around an order of
magnitude less frequent than single packet loss, although they do
occur more often than would be expected from a purely random process.
Longer burst losses (of the order of tens of packets) occur
infrequently. These results are consistent with a network where
small amounts of transient congestion cause the majority of packet
loss. In a few cases, a network link is found to be severely
