I apologise for the commercial slant I gave to my reply to Jill's original
question on this.
It has already clouded the issue, to judge from one response.
So let's start again, it is too much fun to slang about!
I am preparing a set of points which re-visit the issue in terms which
cover the technicalities, while steering away from the commercial
associations and affiliations which we all have, to a greater or a lesser
degree.
I hope to mail this out later today, (kids to bath, stories to read, etc
etc) and will certainly do so by this time tomorrow otherwise.
I hope to get lots of input on this very exciting problem.
Regards, Bob
