Typekit is an upcoming typeface hosting service which will provide vetted fonts that you can include in your site's stylesheet using the @font-face mechanism.
That's where Typekit comes in. We've been working with foundries to develop a consistent web-only font linking license. We've built a technology platform that lets us to host both free and commercial fonts in a way that is incredibly fast, smoothes out differences in how browsers handle type, and offers the level of protection that type designers need without resorting to annoying and ineffective DRM.
What a great idea. And web entrepreneurs pay attention, this is how to make a compelling online property: take an idea that everyone loves in theory but doesn't use in practice because it's a pain in the ass (in this case, embedding type on the web) and offer a hosting service to solve that problem. YouTube did this with videos, Blogger/Blogspot, TypePad, & Wordpress did this with blogs, Flickr did it with photos, etc. etc.
