That would be mad as then other players like WinAmp or QCD wouldn't play them.
Well, even if they did use a DRM that was compatible with Quicktime, they would have to embed it in an MPEG-4 container for Quicktime to understand it. From the Helix Producer manual (which doesn't address DRM'd AAC) they only support AAC audio in MPEG-4, 3GPP, and 3GPP-2 containers. So it is likely that DRM free AAC files from Real will play in Quicktime (since it supports all 3 of those formats). Of course, they could also port their file format and DRM to Quicktime and enable Mac users to use them. Of course they could be using an MPEG-4 container with a format codec that Quicktime doesn't understand (I haven't seen these particular files, so I can't tell you which it is...) but oddly somehow I doubt that...
I just wish it were easier to find stuff on Real's website. It's telling when you need to use Google to find useful information on a website...
Edit: Seems Nermal has discovered that even Real's documentation doesn't necessarily jive with reality
