Design Patterns discussion

Mikal,

One of the specific uses called out for the Bridge pattern is for 
dynamically selected implementations.  Refer to the Bridge pattern, 
"Applicability" section, "Use the Bridge pattern when (1) you want to 
avoid a permanent binding between an abstraction and its implementation. 
This might be the case, for example, when the implementation must be 
selected or switched at run-time".
