Which fonts with good coverage of ancient languages are available as Web Fonts for embedding in web pages?

Beginnings of an answer

 * New Athena Unicode (download) offers a freely downloadable WOFF version of their font that includes many important features for ancient languages (including Egyptian, Arabic and other transcriptions). (For example, the EpiDoc Guidelines has a copy of the New Athena Unicode WOFF at http://www.stoa.org/epidoc/gl/assets/newathu5.woff for display of certain poorly-supported characters.)
 * Cardo (information) is a large Unicode font specifically designed for the needs of classicists, Biblical scholars, medievalists, and linguists. It is licensed under the Open Font License.
