It's not meant to solve the problem of running 32bit and 64bit _binaries_
simultaneously. It's meant to solve the problem of installing 32bit and
64bit _libs_ simultaneously.

You're trying to solve a different problem.

But we never allowed that! Except for broken packages which keep binaries
outside /bin directories. That's a major change of functionality, hence
my saying that's a different problem.
