Yeah, I will pick it up (unless Jacob's already on it?)

I believe we've agreed that it'd be sufficient if we allow the
packets exchanged during the auth phase to be up to 64K or so,
but once we reach the point where we're able to split the
data on arbitrary boundaries, keep the packet size at 16K
for cross-version compatibility.  I did look at the code
briefly, and this seems like it'd require releasing and
re-alloc'ing the buffers, but that's surely doable.
