Have you tried running Sphinx on these docstrings? I would wrap the
tuples in ``...`` and drop the curly parenthesis around the subscripts.

+A share in the Orlandi runtime is a 3-tuple (x_{i}, rho_{i}, Cr_{i}) of:
+- A share of a number, x_{i}
+- A tuple of two random numbers, rho_{i} = (rho_{i}_{1}, rho_{i}_{2})

+
+The :class:`Runtime` operates on shares, represented by this class.
+Shares are asynchronous in the sense that they promise to attain a
+value at some point in the future.
+
+Shares overload the arithmetic operations so that ``x = a + b``
+will create a new share *x*, which will eventually contain the
+sum of *a* and *b*. Each share is associated with a
+:class:`Runtime` and the arithmetic operations simply call back to
+that runtime.

+Each player in the protocol uses a :class:`Runtime` object. To
+create an instance and connect it correctly with the other
