No problem, I've been busy with other stuff too. Just as a side note,
I haven't forgotten about the driver domain series too, and I will try
to answer the questions/suggestions as soon as I can.

I don't think it needs autoconf 2.67 (or at least I'm not aware of
using any specific macros that require > 2.67), but since autoconf
should only be used by the developers, if someone has to generate a
new configure with a previous version we could always try to downgrade
the prereq and see if it works.

I'm aware, since the yajl 2 series went in, this patch needs some
adjustments. Just drop a line when you are ready and I will update it
to match tip.

Thanks, Roger.
