        A. Kutzner, M. Schmidt-Schauß,
        "A Non-Deterministic Call-by-Need Lambda Calculus" (.ps), (.ps.gz),
        International Conference on Functional Programming 1998, ACM
        Press (available at
        http://www.ki.informatik.uni-frankfurt.de/papers/schaussbib.html) 


does address some of the issues involved in providing a theoretical
foundation for non-deterministic functional languages. It does not
address logical variables and IO though.
