Well, I think Matthieu has a valid poit, you should try to come up with
a set of advantages, otherwise why would this drivers be needed? Why
would people spend time reviewing it? May be less memcpy's? Do we do an
extra memcpy in gluebi? If yes, can we avoid doing this. Anyway, please,
try to sell this driver a bit better.
