I don't think that's correct. At least in R5 all Add*() methods are merely 
thin wrappers that invoke AddData(). They don't do endianess conversion -- 
I believe it's only done when unflattening a message.

There're only a few of those methods that do more than directly invoking 
AddData() with a pointer to the data and its size. The complete list should 
be: AddRef(), AddMessage(), AddFlat(). And each of them renders the flat 
data into a temporary buffer and then calls AddData().

Personally I really don't understand why Erik unleashed his template 
madness when things could have been so much simpler.
