The LDM system can send zero-sized data-products. However, because the MD5 
checksum of the data-product will be the same for all such products, you'll 
only be able to send it once. After that, you'll have to wait until that 
data-product is purged from the product-queue before you can send it again.

One workaround would be to have the data-product contain a timestamp whose 
temporal resolution was finer than the minimum time-difference between product 
insertions.

Another workaround would be to use "pqinsert -i" (rather than ldmsend(1)) to 
insert the zero-sized data-product and then ensure that the product-identifier 
was unique.
