20081021: LDM CUP->TYPHOON, quick comment about LDM-6.7.0

The LDM-6.7.0 release notes include commentary on the changing of
the primary name for the FT27 feed type from NNEXRAD to NEXRAD3.
NNEXRAD is still, and will continue to be a viable alternate name
for this feed.

This change was made in response to a request by the NWS to
be assigned a LDM/IDD feedtype for their distribution of full RPCCDS
products to "customers" that had been getting the data via multicast
over dedicated T1 lines that the customers had to pay for.  It
took us a little while to convince the NWSTG folks that that data
was a natural fit to the NNEXRAD datafeed type since it is used
to identify Nexrad Level III products.  We changed the name to
better indicate that the content of the datastream is Nexrad Level
III (NEXRAD3) data regardless of its source (NNEXRAD indicated
Nexrad Level III from NOAAPort).

Cheers,

Tom
