Another contender in the sIFR / Facelift Typography Arsenal
It seems to use the PNG image format so it will support transparent backgrounds, however the text is not selectable in most browsers (a feature that sIFR has). What really catches my attention is the capability to use font-stretch support, giving you the ability to render condensed, semi-condensed, expanded, etc font styles.
Additionally it does have some support for line-height and letter spacing, two features that FaceLift doesn’t appear to have at the moment.
If anyone has used it leave some feedback and let us know how it works.
