1. It is interesting that a response to this message from DrMajorBob 
appears in my newsreader approximately one minutes before the message 
itself.  So either AK and DMB either have early access to the newgroup
or (more probably) are corresponding separately.

2. If you wishes to characterize complaints on the newsgroup as "no 
evidence at all"  then quite a few suggestions should be ignored.

Talking about "no evidence".  What could I hypothesize about you, based 
on no evidence? I'm afraid SteveC would (correctly) censor it!

For your information, the lisp program MockMMA  (are we allowed to 
mention this here??) has been used by a few people for system building 
projects of various sorts. From a Google search, a note back in 2001 says
"It's used in Tilu   http://torte.cs.berkeley.edu:8010/tilu .
There are about 40 people who have downloaded copies and told
me they did so; one person apparently used it as the basis for
an NSF small business grant".
{Tilu, after running about 250,000 queries, over a few years, was shut 
down.}

As far as YOU can tell.

Many? Really? On the other hand, you are not counting the ones who wrote 
to me off the newsgroup, in favor of the idea.

I did not know that you were an expert on business practices. Would you 
therefore recommend that airlines stop carrying lifeboats on Boeing 
747s? They've almost never been used (perhaps never? I think crashes 
into deep ocean water result in 100% fatalities).
