  Some time ago, Tseytlin has made an original and unusual proposal for an
action that eliminates an arbitrary cosmological constant. The form of the
proposed action, however, is strongly modified by gravity loop effects, ruining
its benefit. Here I discuss an embedding of Tseytlin's action into a broader
context, that enables to control the loop effects. The broader context is
another universe, with its own metric and dynamics, but only globally connected
to ours. One possible Lagrangian for the other universe is that of unbroken AdS
supergravity. A vacuum energy in our universe does not produce any curvature
for us, but instead increases or decreases the AdS curvature in the other
universe. I comment on how to introduce the accelerated expansion in this
framework in a technically natural way, and consider the case where this is
done by the self-accelerated solutions of massive gravity and its extensions.
