The experts will have to answer this more carefully, but I do get the impression that this is indeed the issue: Michael Downes says that small fonts, as used in indices, do require ``optically scaled'' fonts, as opposed ``propostionally scaled'' fonts (if I got the terminology right). So how should one then be able to break out of the use of CMR only, if in addition the text fonts should match the math fonts, and how far can you pragmatically get there? And so on. So you cannot simply flip in some proportionally scaled Adobe fonts, and expect it to work. Hans Aberg
