thinking about (b)... Debian splits packages after they've been built, 
so we know that it can be done (they'll make sure of it).  The 
difference perhaps is that we'd put the different parts in different 
prefixes.  So we really should, for example, pass a different --docdir 
to ./configure than --prefix, which "should" make things work (probably 
with some build-systems and even some configure-based, there will be 
things that don't quite work right, so maintenance-work can at least 
help upstream fix those... at least, that philosophy towards upstream is 
GoboLinux's...)
