I like the terminology of G1, even if we don't have checkpoints for device-independence. You are supporting device-independence when you do the substitution of input devices. It's ok to have an over-reaching Guideline 1. I think the summary should give a different view of the document. I think we need to be alerted when there are no more instances found.
Additional techniques are welcome as well.
Propose text for the techniques document about synthesized speech implementation issues. Notably UA and AT wanting to use the same synthesizer engine. Report to WG on discussions at Microsoft about keyboard emulation. I got a lot of shrugs and little interest about this. I'll send a synopsis.
