It's in GStreamer at least:

http://webcvs.freedesktop.org/gstreamer/gst-plugins-good/gst/rtp/gstrtptheoradepay.c?revision=1.4&view=markup
http://webcvs.freedesktop.org/gstreamer/gst-plugins-good/gst/rtp/gstrtptheorapay.c?revision=1.6&view=markup

The document is authored by Xiph, the same people that developed Theora
in the first place.  Seems like that would be a pretty authoritative
source...
