The easiest way to do this is to attach a restrictive license or
no license to your code for the first 24 months, then release it
under a less restrictive license such as the BSD license.  For
most purposes, you don't need an uber-license that covers the
terms both before and after the 24-month period.  It's your code,
so you can change the distribution terms as you see fit (aside
from being able to revoke privileges granted by an earlier
license.)
