Hi all:
This “technique” hint is intriguing and I will not doubt be trying it out.
Spatialization is not always possible (and there is always the demand for
“stereo” mix-downs for CDs) This makes having these hints valuable
knowledge.

you can use low-pass filters to simulate 3D locations: for instance, if you
filter out a lot of the high frequencies in the left channel and leave the
right you can get interesting results on headphones. in ideal conditions
this would give the impression that the sound is "behind" you on your right.
  the other thing too is experimenting with adding a very slight delay to
one channel (not an echo... but actually like a 1-25ms lag)
and perhaps using inversion...one inversion-related trick that i discovered
through using cool edit pro's "channel mixing" feature ;-) (laugh all you
want). By mixing a bit (10% - 50% of the original volume) of an inverted
right-channel signal into the left, and a bit of an inverted left-channel
signal into the right channel, you can achieve a widening effect, which can
be quite effective. due to cancellation, this can either making the sound
louder or quieter, but it can still be quite effective.
you can get interesting results from combining all/ any of the these in my
experience. inverting one channel which is slightly delayed for instance...
