It's a nice thing, but how is that relevant to the discussion about texvc images? Formulas don't need several transparency levels.
Yes, they do, if you want them to look good, because the fonts are antialiased.
The problem of black background by browsers* ignoring the alpha channel is solved by using a white background with alpha transparency. So people not supporting the alpha channel, still see it white (for some reason, image software like putting black as the color being 'transparent').
This means that you'll still have a fuzzy white outline around the text when you put it against a non-white background. However, you're right that this will probably look better overall than the current situation. It's worth considering.
*It's not just printing on IE6, the alpha channel is also ignored if you open the image with simple software like paint.
I think we can ignore this issue.
