For example, if you would be able buy HD-AAC in the iTMS and then let it copy just the AAC-LC part to your iPod.

This would seem to be the simpler solution as it utilizes an existing format, allows the end user to choose the AAC bitrate, and should also be more efficient from a downloading and storage standpoint (assuming the HD-AAC files would be larger than ALAC due to their hybrid nature).
I heard/read somewhere that the compression performance of HD-AAC is supposed to be on par with FLAC and similar dedicated lossless coders.Chris
One can wonder what the use of MPEG4 ALS is once you have SLS.
Garf: Will Nero release an encoder capable of utilizing this?

People started doubting that they were hearing decoded full DTS-HD MA even though the programs (commercial bluray players like TotalMedia Theatre and PowerDVD) were saying that they were decoding it.
You know, if only for the ridiculous ease of use when managing my iPod. Hope Apple will use this!
MPEG4 SLS (HD-AAC) will win if you need to transcode, because it only needs minimal processing to "slice" the stream to the bitrate you want, and the AAC or AAC+SLS layers are backwards compatible to LC-AAC.
Wasn't he previously? I don't remember too well Who is? (you maybe?)
The more I think of it: with HD-AAC gaining in popularity, I think LossyWAV will have a very powerful contender.
I quit Nero about 3 years ago.
Both the HD-AAC and the sliced LC-AAC file can be played back on a legacy device. The LC-AAC portion of the HD-AAC file is only encoded once, though. So you can only slice a new file out at the bitrate that was originally encoded, e. g. 256 kbit/s. For other bitrates you need to re-encode the lossless data.
I think, if Fraunhofer wants this to be a success, they must have an unlicensed encoder and decoder out in the wild soon.

No need for Fraunhofer for that. They're just one firm that implemented it, and try to sell their codec which is named HD-AAC. Just like the HE-AAC standard was sold by Coding Technologies as aacPlus.This standard is probably covered by a boatload of patents, and will for sure be covered by those for LC-AAC. Fraunhofer doesn't have any particular decision power about how they will be licensed.
Microsoft and Adobe have build monopolies on business facts like that. But I don't have much hope for Fraunhofer. Those institutions usually don't have the organizational structure, where a decision like that can really be made. Scientists are used to having to cover their asses consistently for every step into the unknown. And who would voluntarily take responsibility for a step like that. By contrast for real businesses like MS and Adobe taking risks is routine business.
