Hi Michael,
You might look at our paper
Scheirer, E. D. and Kim, Y. E. "Generalized audio coding with
MPEG-4 Structured Audio." Proc. AES 17th Conference on
High-Quality Audio Coding, Florence, IT, pp. 189-204.
This is available from my WWW page
http://sound.media.mit.edu/~eds/papers.html.
A longer version will appear in IEEE Transactions on Speech and
Audio Processing later this year.
This paper doesn't provide any direct practical solutions, but
presents a framework that I think is the right way to develop
new coding techniques leveraging the strengths of the SA
format.
On a more practical note, I'll be developing a cross-coder
for the Vorbis open-source compression library (www.ogg.org)
into SA sometime later this summer.
Best,
-- Eric

Subject: MPEG 4-SA for audio compression?
