  The technology exists, but USB wasn't designed to work that way and so
there's more to it than just plugging in a standard cable.
  USB was designed to connect one computer as "master" to a bunch of devices
as "slaves".  The master supplies not only control signals but also *power*
to the USB bus.

  So it takes some combination of special cable and software to make a
working PC-to-PC USB connection.  This is a case where I would buy a
commercial package rather than try to re-engineer it myself.
