That's why the world does it ! :-)
I was hoping for some comments from people who had tried it 
in practice, but papers like that one are a good start :-).

Interesting.
Some good references too.

This paper makes the interesting, and retrospectively 
obvious when the diagram is examined, point that a rapid 
change in delta insolation may cause a perturb and observe 
algorithm to initially wander off in the wrong direction.

Doing it is easy. Handling the implications and the patents 
may not be.
