The second multiple design pattern is an implementation of the Symmetric Proxy
pattern. The Symmetric Proxy uses a Template Method pattern (Chapter 9) and the
Proxy pattern, a pattern not covered in the book. We used Flash Media Server 2 for
delivering the moves into a proxy method residing in a player class instead of a sepa-
rate class for the proxy and real player. However, the Symmetric Proxy, like all good
designs, is resilient enough to accept these changes without losing its own basic
structure or function.
