I feel it important to make the minor side-point 
that the "Remebee" product is targeted at ONE virus, 
IAPV, so while one could go through the same process 
for multiple viruses and mix the resulting "serums" 
into one product, I haven't heard anyone make the 
claim that any one "Synthetic Small Interfering RNA" 
would be effective against any more than one 
specific virus at any one time.

There are a number of viruses that are variants
of other viruses, so perhaps one could target
something like KBV, and, in the process, sweep
up all the KBV variants, such as IAPV.  I'm 
guessing here, as I'm >>NOT<< any sort of 
microbiologist, but there has to be a number 
of genetic snippets common to several viruses, 
and if one targeted one of the common snippets, 
then what Peter suggested might then become true, 
and one siRNA or shRNA could frustrate multiple 
viruses.
