1) Is that true, or is HLS intended to now support AC3 passthrough?
HLS is intended to now support AC3 passthrough.

It does not have much testing on Roku 1 devices. (Nor much testing on Roku 2 devices, but at least developers are reporting success there).
3) If intended to work on "classic" boxes, does it actually do so? If not, any insights into when it might?
No insights at this point. I would welcome a stream to debug on the Roku 1 devices. Please send me a PM with your hls stream url that includes 5.1 audio and has trouble with playback on Roku 1 units.
4) Is AAC-LC intended to support 2 channel stereo audio only? (In theory AAC supports up to 48 channels, but I'd settle for 5.1...)
Yes. AAC-LC support is for 2 channel stereo audio only.
