I worked with Steve to get it working.  He will be making a CVS
snapshot of the latest swh-plugins that you can download (or he
sent you a binary .so).
 
There are two version, a 4-in/2-out and a 4-in/4-out.  You want to use
the 4->4 plugin in ardour, and add it to a 4-in/2-out bus.  You
will see 4 stereo panners in the strip, and you should pan them,
hard L,R,L,R.  Then route your stereo input A to the first two
channels, and input B to the second 2 channels of the bus.  The
plugin single control will then xfade the way you want.
