Modern browsers and modern OSes will anti-alias the fonts, if you 
turn on the option (apparently it can sometimes make things worse)

What's font streaming?  CSS provides a framework for font downloading,
but doesn't specify the font encoding technology.  Problems are:

- I don't think grayscale fonts are allowed, so you can't anti-alias
  without an anti-aliasing font engine!
- there are two standards (roughly IE and NS4, although I think the
  situation is more confused and NS6 doesn't support the NS4 format
  and may not support the IE one;
- any font delivery mechanism has to meet the copyright protection
  demands of the font foundries - this means some fonts can't be
  downloaded and, for the other fonts, the font delivery mechanism locks
  you into viewing the page from one site, so you can't locally mirror.
