They’ve been out for over a year, but I just stumbled upon them this week. Redhat release some very high quality and non-encumbered fonts. Most distibutions will have them in a package named liberated-fonts. They are substitues for some very popular fonts such asTimes New Roman, Thorndale, Nimbus Roman, and Bitstream Vera Serif.
