Er. lots of things.  Exchanging messages with a web server via HTTP is
commonly regarded as substantially easier than dealing with low-level
socket library.  Furthermore, writing your application dispatch in the
context of an existing web server is commonly regarded as substantially
easier than setting up a connection management & dispatch facility 
yourself.

And I agree that in the general case, it's weird that being able to
penetrate firewalls is seen as a benefit, but that's life.  -Tim
