Well, you can't use a transparent GIF either. To anti-alias an image or a piece
of text, you have to know the background. When you anti-alias, you make the
pixels around the edge have some colour in between that of the letter and that
of the background. If you put an anti-aliased image on a multicolored
background,
those pixels will stand out from the background and look very peculiar.

But the proposal is interesting, since it addresses an existing need. I myself
use anti-aliased text on pages I design - they look much more appealing
that way.
