#Font and #type nerds - where can I find something quasi-definitive about Adobe's "SING"/"Glyphlets" tech?
All that I turn up in normal search avenues is ancient and in non-standard material, like an isolated PDF that claims to be a presentation from a conference. Better than 50/50 that it's legit, but that's still far from an authoritative source of truth you would cite.
Yes, it seems like the format is no longer actively developed, but this is for reference purposes.
