Nice find - I love it when that happens.
BTW, the full treatment of these JFET buffers is given by Erno Borbely in his JFET part II article from '99. He gives credit to John Curl for the circuit I have been describing, and says it is one of two favorite types. The other is similar to to the circuit that used a dual N type matched pair. see

on the third page is full boat on buffers. His output impedance is a lot lower than mine, but still advises you to keep it at 1kohm or higher loading.
