Martin, that's a very insightful article about the LM317. Have you looked at the new LT3080 regulator? It's designed have the reference pin driven be either the classic resistor, or with a zener, or a voltage reference, or even driven actively. Very cool, and achieves what you're talking about with the REF resistor on the LM317.

Peranders (Sjostrom) regulators are among the quietest I have tested -- using the AD797 or LT1028.
