Correct.

That will allow Oliver and Emo to request NEXRAD2 data-products from you.

You don't need any of the above. All you need is the "EXEC rtstats ..." entry 
in your LDM configuration-file. That, by itself, will cause rtstats(1) 
data-products to be sent to us. We're already set-up to accept incoming 
rtstats(1) data-products from you.

rtstats(1) data-products are usually not requested by an LDM (i.e., there's 
usually no "REQUEST" entry in an LDM configuration-file for rtstats(1) 
data-products). Instead, such data-products are "pushed" by the rtstats(1) 
program "out of the blue" to an LDM server that has an "ACCEPT" entry in its 
configuration-file that will allow the incoming data-products to be received 
and, consequently, processed.

Use the "-h" option of rtstats(1) to send its data-products to an LDM of yours 
that has an appropriate ACCEPT entry, e.g.,

    ACCEPT EXP "^rtstats" "\.gov$"

The rtstats(1) program has a manual page.
