Things like transcoding for different sizes / mobile as well as DVR style seeking/recording.

Ogg Vorbis was designed with bitrate shedding in mind (drop bits from packets to get a lower bitrate), though I'm not aware of it being used. Are there any bitrate shedding video codecs? If not, one could be developed that allows low-bandwidth clients to request only a percentage of the blocks of a stream and decode a low-resolution/low-quality image therefrom.
