  We suggest that the (small but nonvanishing) cosmological constant, and the
holographic properties of gravitational entropy, may both reflect
unconventional quantum spin-statistics at a fundamental level. This conjecture
is motivated by the nonlocality of quantum gravity and the fact that spin is an
inherent property of spacetime. As an illustration we consider the `quon' model
which interpolates between fermi and bose statistics, and show that this can
naturally lead to an arbitrarily small cosmological constant. In addition to
laboratory tests, we briefly discuss the possible observable imprint on
cosmological fluctuations from inflation.
