I might be able to make a contribution here.  Recently, I completed a
paper on combined random number generators, "Quick and Portable Random
Number Generators," with Dr. Gerald P. Dwyer, formerly with Clemson
University and now at the Atlanta Fed.  The supporting random number
generator is very well behaved and has a period of about 2^62.  This
is certainly long enough to outlive the expected life of the universe.

Any interest?
