Absolutely. I think it was a mistake to change that value.
But I don't think we need to reintroduce the htohl(). That
was just one way of doing it. If I understood your suggestion
from yesterday correctly you converted the whole message within
one if()clause, without any htohl(). I have have no problem with 
that approach.
