Is this vaguely similar to "stereo microphones" that some walkman's come (or came)
with?  I once had an Aiwa walkman (yes, I know I "crossed brands") 
who's singular microphone (about 0.75 inch cube) had a strong separation
between the two channels -- with each microphone in the cube having a
strong non-crossing cardioid pattern each about 45 degrees off the "front"
(one left and one right).

What I  had in mind for "surround sound" was two sony walkman's each
with a microphone of this type with cardioids going out in each of four 90
degree separated directions.  Actually two of the old Aiwa's would be 
perfect except that they were bigger/heavier than the newer Sony's which
are barely bigger than the cassette that goes in them.

This would make the sound recording system small, singular (two walkman's
attached together), with no wires dangling or to set up.  In other words an
actual practical way of doing it w/o any fuss.  Now only if it'd work how
I'd like it to.  :-)

Are those types of microphones now standard (or obsolete)?  I haven't bought
a new one lately.....

P.S. - Any good 3D places in Chicago to visit?  I'll be visiting on business
       for a couple days later this month.
