Actually, I should have said, "accept" instead of "allow".

A caveat is that the client needs to be ready to receive when you send the
product, or they'll miss it (unless you have some way that they can request
that you resend it)  Another is that the filename of the product you send
has to be the same as what you want the header to be seen as on the client
end.  You also have to come up with scripts to send the products when they
become available  (perhaps the scripts could be launched from pqact when
your LDM has received and saved the product to a file that you can resend.)
The upside is that you control EXACTLY who gets sent what and when since you
have to manually specify it all.

I'd strongly caution against multiple LDM's running on a machine since
besides the non-trivial technical issues, the performance is likely to be
terrible unless the products are few and tiny due to cache being spread thin
across all of the queues, plus their overhead.

You could push the product with ldmsend like WSI does with their products
rather than have the clients pull the products. (clients need to add an
allow line to their ldmd.conf)
