I not sure what you mean by "I'm too lame" but it's sad to hear you
won't write a patch. It looks like you have good knowledge in this area
(more than I have, at least).

Could you try to send a patch, please?

Or, "a middle hack not yet finished but giving the keys to let other
finish the work"?

Or at least, a beginning of something like comments highlighting the
lines of code to improve?

Or is there nothing you can do to help us a bit more, actually?
