This things I must read first. But I get slowly a little feeling  
where we are ..... :-)

yes, and I would add, it is also the inability to find something to  
like. Often, I hear "oh yes, ,good idea, but it could be better". In  
the same direction goes  the experience "all things are already  
written in software, but nothing is written which could not be done  
better". And it is interesting - mechanical  engineers would not get   
the idea the build a eletric motor for themselves - if to build a  
airplaine or car...

Yes. And it (the reuse) should be very easy and flexible. But I think  
that's included in what you said.

Thank and Greetings
