  a small electronic financial news distributor in Oslo just purchased its
  second ACL 5.0 license.  so far, the cost of the licenses appears to be
  close to 10% of the total development costs, but that is likely to fall
  as more and more new ideas can _finally_ be implemented, after years of
  wishing without the budgets to implement them.  the license may cost much
  up front, but when you have made this _investment_ it really starts to
  pay off.  e.g., an idea as complex as the initial contract took me a week
  to add after I had spent the summer with a very bright assistant building
  the most elegant piece of software I have ever built, and it would have
  cost at least 20 times more to add it to the legacy C-based system.  that
  was the first time we could really defend the costs of the first system,
  but I knew this would happen, and wishes like this will continue to come
  true.  I think you will find similar stories all over the place.

  ACL 5.0 Trial Edition for Linux is available for no charge for precisly
  this reason.  Windows victims will have to pay for the Windows Personal
  Edition, which I think is both what they expect and deserve.  (neither
  can be used to sell final products.)  this makes it possible for the
  consultant or independent programmer to learn the system in and out and
  only ask his clients to purchase a license.  this is how Franz Inc let me
  get up to speed on Allegro CL.  it is even easier now with the Linux
  offering than it was when I got my personal use license.
