Oh, didn't see that. That's cool! :)

I guess this wouldn't work for Zope's packages in 
${SOFTWARE_HOME}/lib/python because they're not eggs known to buildout, 
but I could add that to my path manually (and when all of Zope is eggs...)

At least if it was optional to install the eggs' script, that'd be nice. 
I guess it won't do much harm if the eggs install their scripts, though.
