web safe fonts

Its quite common now days to have custom type face for web design.

These browser supports TTF (true type) / OTF (open type) format:

• Safari / Webkit 3.1
• Opera 10 / Opera Mobile 9.7
• Firefox 3.5 / Thunderbird 3 / SeaMonkey 2
• Ie9 (maybe?)
• Chrome 4
  

While IE 5/6/7/8/9 supports EOT (embeded open type) format.
@font-face will not work on chrome / safari if font-variant is set to small-cap.
