Yes, that's basically what I am doing now (modulo some other warts 
related to the build_dir thing; I noticed a few bugs when you want to 
put everything, including sconsign and configuration files into the 
build dir). But you do need two scons scripts files for each package 
(don't forget that I am calling a new scons process for every 
subpackage, so I cannot have a top scons script to set up everything).
