I totally agree with Al here and I would add this, the Late Len Kasday
pointed out over and over that no tool can completely check anything for
accessiblity.  It takes human Intervention.  It takes someone who knows what
they are doing to check the results of the tools.

Also Bobby can  be downloaded from CAST. Al is right, you use this tool from
the web for large projects and no one else can use it.  I have had it happen
to me.

Al is also right in saying people should not expect to get a good analysis
for free.  Tbese things take time  and skill.  To expect to get it for free
is totally unrealistic.

There is a question of business justice, here.  It is not fair to rely on
free Web-interactive services such as Bobby at CAST for survey purposes. 

Bulk work such as surveys should be performed with resources provided by the
activity doing the survey.  This is partly where our clunky 'robot control'
system came from.  There have been problems with U.S. activities bringing
free over-the-Web Bobby service to its knees in a de_facto denial-of-service
attack by putting production loads on the web-published service.  Use the
service for samples, please.  Not for surveys or other production runs.

Those who wish to survey should reasonably expect to pay.  There is no
for assuming that people will render you great gobs of service for free.
which is appropriately _de rien_ is in the eye of the service provider, not
