Oh, I at least simply mean on text fields that are formatted, e.g. in CSS, to be password-type fields. It may even be possible to write a hook into the Terminal client, so, e.g. when the user is asked for sudo permissions, it temporarily disables the glow on the keyboard. I'm talking about basic solutions that may not cover all the angles, but can cover the most common points. But heck, it's open-sourced, so I know I could implement something like that myself if I wanted to, so I'll shut up. :P
