Quite fun.  Those concerned with efficiency may note that moving a
fix for lower layer problems into the upper layers is typically less
efficient, but it gets the job done.

A major shift in 30 years is in transmission cost ... the cost per
bit has gone down dramatically since we paid thousands of dollars a
month for a 56kbps line.  This means we can now well afford the luxury
of fixing lower layer problems at the application layer.
