well i can add a success story on bundling and shipping macport libs.
in our project, clam (http://clam.iua.upf.edu) we ship 3 audio-related 
applications with many dependencies (qt3 and qt4 among them).
we created this python script very simple to use:
http://iua-share.upf.edu/svn/clam/trunk/CLAM/scons/sconstools/addDependentLibsToBundle.py

you prepare the bundle and call:
addDependentLibsToBundle( "Annotator.app" )
it will recursively find all dependent (including indirect dependencies) 
libraries, copy them the bundle Contents/Frameworks and change its 
absolute path to the correct relative path.

hope it might be useful to others.
cheers,

pau

ps:
about binaries, we tried but found it too hard. we just have two boxes 
(ppc+intel) and distribute two different packages -powerpc.dmg and 
-intel.dmg. this way you have the bonus that the user downloads half the 
size of a single universal.
