OK, I posted this on the blog, but just thought I'd throw this out here for your inspection.

I searched, couldn't come up with this particular implementation either here or on Google images.

I like it. I mean, throw in a few more resistors over the basic diamond buffer and you can freely control the output stage bias current. Simple and convenient.

Now, there are residual questions regarding offsets, stability, thermal runaway, and so forth, but the FFT at least sims out good.
