If you're using linux or BSD or any real OS that deserves the name, yes.

I don't think you will have much fun with that approach - at least
creating two instances of the same vo currently is not possible.

Don't know what exactly you mean by "attach". You would need to create a either a vo (in libvo subdir) or vf (in libmpcodecs subdir). The functions those modules use are described somewhere in DOCS/tech.
My solution to this is:
In one console do:
mplayer -vo yuv4mpeg <file>
This mplayer instance decodes (and unless you make it use -ao pcm and
feed the sound via another fifo to one of the other MPlayer instances
will also play the sound)
And in another one:
cat stream.yuv | tee mp1 mp2 > /dev/null
And in yet two more (these will display the video):
Probably audio and video will be out of sync like this, in that case you
should have a look at the -ao pcm option and use -audiofile with one of the mplayer instances that do the displaying.
In case you happen to make this idea in a nice, well-working script or
something, please post it here, I'm sure there are others who will be
