The AAC standard has been set since 1997.

AAC is part of the MPEG-4 audio specification.
Apple just has an implementation of that.

If it doesn't produce the same format it isn't an AAC standard conformant
encoder.
AAC files created with PsyTEL, FAAC, Nero, Sorensen, FhG, Dolby and Apple
all play fine with each others decoders.

Peelable? That doesn't work yet, IIRC. AAC can be scalable as well.

AAC is pure VBR as well.

Try the HE AAC codec that Ahead will release on July 18th, it kicks Vorbis
ass at low bitrates.

The MPEG-4 file format supports multiple tracks as well. Next to that AAC
has proper multichannel support.
