Several years ago, we at Cornell started to look into the use of token refresh.
Most of our work was based on code written at CERN back in 1995 or earlier. 
The person who wrote that code is no longer at CERN.  To add to that, the
person who did all of the porting here at the Cornell Theory Center is no
longer working here either.  I do know that IBM expressed interest in getting
our token refresh code so that they would have something they could give to
customers.  My own advice would be to let the LoadLeveler folks know that it
would be quite nice to distribute some sample token refresh code so that every
site doesn't have to reinvent the wheel.  I do know that what we use depends
on sysctl, another piece of software that has no support since the folks who
wrote it no longer work at IBM.
