I have been investigating what in my view is a serious shortcoming and this is what I have to report.
One guy, Bill Waslo, wrote a paper:
... and implemented his idea:
The application is available for free, but it is not being maintained. It only runs on Windows XP, for starters.
Are the questions that we ask here considered to be of a rhetorical nature?
TIA for a reply,

It may be late to answer you, but yes you can. Simply "Invert" a copy of you wav file and "Mix Paste/overlap" it with the original. The result will 0.
Now if you have two different recording, one for a signal A+B and another with signal B to substract that is a bit more complicated as both recording received these signal from different paths. This is likely to cause difference in the frequency response and the phase. Lets suppose it is not the case, you will first need to allign the two recording sources. You can do it in audition 3 using the convolution as shown in this video:
Then, invert the recording with the signal B and "Mix Paste" it together.
You may want to do more search on the adaptative filtering and the RMS, LMS filters if you are interested in compensating for the different audio path.
