There is the possibility to rewrite the internals of property_tree with 
Boost.MultiIndex, and then it could use a hash-index instead internally.

Why is having no search so important. How does it hurt you that it is 
there? (if the small overhead is not important anyway)

What does this mean? versioning ala boost.serialization?

(aside: I think it would be reasonable for ptree to be serializable)

What does this mean?

We can also keep adding customization to a component until it suddenly 
collapses under its own weight.

Gennadiy, I hope we can avoid too much flame-wars. And I hope we can
to the buttom of the problems you mention s.t. you also would want to 
use this library (unlike PO).
