I really don't think anyone here would NOT be interested in something like this, from many perspectives. From being an "Andy fan" to strictly for learning purposes I think it would be cool. I think many of the kneejerk reactionaries here are more so thinking it would result in "clones" of how Andy does things, which may be the case for some. But, as someone who has not taken any kind of training for AE, I'd love to be able to get a true glimpse as to the how and why reknowned AE's do what they do and compare/contrast how I attempt to make a quality audio product that falls in line with "the big boys".
That said, with things like "Rock and Roll Summer Camps" and whatnot, I'd jump at the chance for something similar (albeit perhaps more one on one) with well known engineers...But I suppose that's what interning is for, eh? But, for those of us with regular dayjobs (i.e. not in a studio), I'd love a 1 or 2 week interning session or "summer camp" with someone like Andy as thy go through the paces of making a rekkid.
