I think that allowing multiple owners and ref-counting is the right thing to 
do. However, I also believe that librpm had better check that the files are 
identical (judged by size and md5 sum) before it allows the overlapping 
install. Nasty consequences are likely if this is not enforced.

With x86_64 multilib dual ownership allready occurs in rpmdb, for example:

# rpm -qf --queryformat "%{name}-%{version}-%{release}.%{arch}\n"
/usr/share/man/man3/zlib.3.gz
zlib-devel-1.2.2.2-5.fc4.x86_64
zlib-devel-1.2.2.2-5.fc4.i386

Not sure how that works today, though.
