PGM does it out of the box too, and is technically a generation ahead
of NORM.  It's built into Windows 2003 and newer, with acceleration
support in every Cisco, Juniper routing device in the last few years,
it is based on TRDP which is probably the worlds most deployed and
proven reliable multicast transport.

There's another implementation of NORM here:

Most of the development work from NORM has been on improving the FEC
overhead to get closer to the Shannon limit of the channel, namely
using LDPC over a very large data set.  This resulted in it's
selection for DVB as it works well with no back channel.
