/me wonders if I'm merely duplicating something they've already done in the 3.0 trunks

Even if you are (and I may be stepping outside of NDA to say this, but this is the first I've heard of auto-EQ in reference to the 3.0 trunk), 3.0 is pretty far off, so I think there would be significant benefit to having a 2.0 auto-EQ feature right now.

And since it's a personal project of John G's, perhaps you two could correspond and compare notes.
