[orca-list] minimal boot-time setup for audio-based interaction?

[Rich Morin <rdm cfcl com>]

A recent thread (Which GUI environment works best with Orca?) is coming very close to a question I've been 
pondering recently: How to define a minimal boot-time setup audio-based interaction?  That is, it should 
allow a blind user to boot and operate any Linux system, as long as a keyboard and audio output are available.

This would allow the user to get started on a freshly-installed system, make any desired configuration 
changes, and then add packages such as BRLTTY, Emacspeak, etc.  By way of background, I'm mostly interested 
in supporting this on hardware platforms such as the Raspberry Pi and commodity PCs.

I had thought that this would require a specifically console-based screen reader such as Fenrir, but it 
sounds like Orca might actually suffice.  Could someone clarify this for me?  Going a bit deeper, what other 
packages (e.g., ALSA, eSpeakNG) would be needed to produce a functional stack for audio-based interaction?

Inquiring gnomes need to mine...
