Thanks. >I'm not sure you'd ever want to relax the echo feature when >dealing with the web however. Sometimes "on the web" is on a cell phone, where text entry is a fiddly, error-prone business. In this case being able to enable earpiece audio echo and review of what you have entered could spare users a lot of "account blocked -- too many bad login attempts." Bottom line: I think it takes a fresh look; can't guarantee if there would be sufficient cause to open up the echo to an appropriate audio channel. But I can't quite rule it out, either.
