A vaguely related feature is provided by ov_crosslap().  Quoting from
the docs:

"ov_crosslap  overlaps  and blends the boundary at a transition between
two   seperate   streams  represented  by  seperate  [1]OggVorbis_File
structures.  For  lapping  transitions  due to seeking within a single
stream  represented  by a single [2]OggVorbis_File structure, consider
using  the  lapping  versions  of  the [3]vorbisfile seeking functions
instead."

(Until I pasted that into my email program, I never noticed that
"seperate" was misspelled...)

Anyway, crosslap does not do the sort of volume fading that a crossfade
implementation would do, but I thought I'd point out the feature in case
you find it related to your needs.
