I have posted this repo (sorry for the delay Craig).

http://code.nsnam.org/raj/ns-3-rng-changes/

Please see the tip changeset:

Michelle's student Hadi prepared this, I simply posted it for him
(with some minor changes to end of line encoding and removing some
unneeded "ns3::" scope).

As far as I can tell, it currently doesn't compile, but I figure that
getting the jist of the patch out to developers for review was
important before merge week began.  I will summarize the list of
changes that I can see in the patchset:

1.  RandomVariableBase::UseDevRandom and associated functionality has
been removed.
2.  RandomVariableBase has new APIs for getting the seed and run number.
3.  Functionality of time-based seeding has been removed.
4.  All RandomVariable classes have removed the GetSIngleValue API
5.  UniformVariable has a new API which is like GetSingleValue
6.  The Box-Muller transform algorithm for NormalVariable generation
is modified (?)

It would be useful if Hadi and/or Michelle could comment on these on
the list.  My one concern with the changes lies in the fact that the
UniformVariable retains a "GetSingleValue" type of API, while no other
class does.
