An interesting read: A List Apart has a recent article by Håkon Wium Lie (CTO of Opera Software) which demonstrates the use of True Type Font support in CSS. I'm really surprised that this isn't already supported by major browsers Gecko. With the major text rendering changes in Firefox 3.0 (plus cool new features such as APNG) I'm confused as to why such a seemingly important CSS feature is not implemented in Gecko. It turns out that there is a bug (#70132) which was filed in 2001 and is aparently not getting much attention. Is anyone interested in working on this?

Update:

I just noticed that WebKit has recently added support for @font-face

Update 2:

Just read a really good article by John Resig covering the state of Web Fonts and the support available in the major browsers. I'm a big fan of John's work and his writing, needless to say, his article is worth checking out!
