Small Caps versions of common web fonts

I've been thinking further about fake small caps after my post on it last week. CSS is part of the problem too, with its font-variant: small-caps property. I did a cursory check, and none of the browsers use the true small caps characters, even when they are built-into the font.

So what we need are freely-licensed small caps versions of all the common web fonts: Helvetica, Arial, Verdana, Georgia, Times, Tahoma, Trebuchet... Once we have that, we just need the browser to use these fonts when font-variant: small-caps is applied. If the browsers don't support it natively, we could write extensions to do it, much in the same way I described my idea for a font-family service.

Surprisingly, there doesn't appear to be any small caps versions of these common fonts (even Helvetica!), except for Tahoma. Although I've had practically no experience creating fonts, creating small caps version seems like a bit easier task than creating a new font from scratch. I might give it a go. Anyone else interested?
