I don't recall any formal comparisons
between FTP and the LDM because the LDM is designed for fast,
automatic delivery and processing of continuously-generated 
data-products throughout a network of cooperating systems; whereas,
FTP is merely a file-exchange mechanism between two systems.  To
make a comparison meaningful, FTP would have to be considerably
enhanced in order to bring it up to the level of the LDM.

The National Weather Service does (or did) have a data-product 
distribution system based on notifications and FTP and (I belive)
some sort of scripting language to tie it all together.  I think
it might have been called NWSnet or NOAAnet.  I note, however,
that the NWS, nevertheless, uses the LDM to operationally distribute
NEXRAD Level II radar data.
