overlay not works

I can also confirm that this does not work. Steam and some games are built as 32 bit applications and the Mumble overlay only contains the 64 bit builds (on the 64 bit version of Ubuntu). The 64 bit library can't be linked to the 32 bit binaries. What we need is the 64 bit version built with the ability to link with 32 bit applications, either as a separate library or some type of wrapper.

I've been wanting to break out the Mumble overlay into it's own
multiarch binary "mumble-overlay" package for a year (I'm the maintainer
of the package in Debian)... unfortunately it's not entirely clear how
to work this out and I find the documentation for multiarch a bit daunting:

   https://wiki.ubuntu.com/MultiarchSpec

If a "mumble-overlay" package is marked "Multi-Aarch: same" to allow
installation of it for both amd64 and i386, how does the user choose
which architecture of the overlay to load? [Thinking out loud: could
this be done via LD_PRELOAD ? How much of a headache would this be for
the user?]

Alternatively the package could be marked "Multi-Arch: foreign" which
would allow loading the i386 "mumble-overlay" on amd64, but then
"mumble-overlay" can only be installed for *one* architecture, so if the
user then goes to play an amd64 game they'd need to know to remove the
i386 package and install the amd64 one, which is confusing and rather a
headache.

I'd like to figure out a way to do this that isn't difficult for the
user to use (and that won't create a support headache).

Let me know if you're willing to test a Mumble package (that isn't in
the Ubuntu or Debian repos) that attempts to do this.
