Hi,

During the past few months, some of us discussed here the posssibility
of adding time-limiting provisions to sets of restrictions in the
license. Look at the thread starting at this post:

  https://lists.ibiblio.org/sympa/arc/cc-licenses/2011-December/006453.html

I feel one of the discussion's most important points was precisely
this topic. Has it been completely abandoned? I could not find any
reference to it in the pages linked from the one you mention.
