new config container?

hi do you need another config container class? i need a class that supports reading/writing (xml container can`t do that) and nested blocks (ini file can`t do that afaik). so i wrote simple container [20 lines of code? :)] that operates on wddx files. for now only Config_Container_wddx::parseInput() and Config_Container_wddx::writeInput() are supported (and i dont know how well are they done :) - im just trying it). my question is: do you want the class to be written? will it be useful for someone except me? the files will have to have strict structure to work ok with existing Config methods - blocks names with '/' at the beginning etc. if anybody wants to take a look: http://rashid.ds.pg.gda.pl/wddx.zip - code isn`t commented, its mainly copied config_container class code. rash
