According to excerpts of Devine's 11th Hour development journal published in Wired at http://www.wired.com/wired/archive/3.08/shipping.html, the RoQ format was named after Devine's newborn daughter, Roqee.
FFmpeg encoder is based on the Switchblade roq encoder which was originally at http://icculus.org/homepages/riot/ . Its author continue the development of the original code.
The RoQ files used in The 11th Hour and Clandestiny are a superset of the format used in Q3-Engine based games. They include chunk types not used in Q3 and supported in the current implementations of the format. These two games, among other differences, also include support for JPEG encoded keyframes.
Games Using RoQ
These games are known to use the RoQ format, often because they are based on the Quake III engine.
