Someone in this list thought the paper was interesting enough and asked me to publish it also in Ada Letters. Now I've got the permission from Ada User Journal to publish the paper also in Ada Letters, but only after it has appeared in AUJ (this will be in the July edition). So under the precondition that Ada Letters think the same and accept it, it will appear in Ada Letters sometime in the second half of the year.
