Total agree. Amaze of close thinking .
I do some similar a time ago, of course not as good.
Could be viewed at ftp://squeakros.atspace.com/, I send user and pass if you
wish.
I don't have the luck of you have my physical teacher, only the luck of work
with you now.
I want all what you Maurice and Navodit wish share with me !
I have a "normal classes" database and a "compressed classes" database,
As you could see , this was of 3.8 times and could be useful today.

And I wish work. Never I said otherwise !. Only wish a few fun...

Cheers
