# The ultimate convenience: decorate TCP/IP servers relevantly according
# to its runtime environment (development/production) and the degree of
# privacy of its network address: personal , private or public.
#
# Wether it's an HTTP or an SQL server, enforcing resolution and connection
# limits is an aspect of the same application: TCP/IP access control. This
# is one obvious way to do it right, conveniently provided as an extensible
# function (you can replace the default resolution decorator).
