Theory? Who says anything about theory? I actually *do* this,
although not in /usr -- I'm not completely insane. The whole lot
is then NFS mounted everywhere, and a clever profile script then
adds the appropriate directories for the current architecture to
$PATH and $LD_LIBRARY_PATH. This isn't as trivial as you might
expect, particularly as it handles emulation, so if I'm logged into
my sparc/linux machine, I not only get the sparc/linux directories,
but also the sparc/sunos ones too, and sparc64/linux gets both
sparc64/linux and sparc/linux.

That said, I don't currently use a package manager to maintain it...
