Fraunhofer pushes HD-AAC. iTunes 8 support?
HD-AAC PDF
HD-AAC is based on MPEG4 Scalable to Lossless (SLS) technology. This appears to allow you to encode a Near Lossless or Lossles audio file yet extract a core "Lossy" component for streaming.
This could be ideal if Apple revamps Apple Lossless Encoding to support this scalable feature. I'd love to have my iTunes music in Lossless yet still be able to push out a lower bitrate lossy file to selected iPods.

In the professional music sector,
HD-AAC enables lossless storage and
editing of music data at sampling rates
up to 192 kHz. From the same file, an
AAC version at 48 kHz can be streamed
to portable devices.
