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.
