Beware, you are entering the twilight zone. This is the direction
'adaptive' system take -- very active research area in CS. 

This is just another tool for enabling adaptation in the overall system.
Adaptation can be built into an application, true, but most application
developers wouldn't bother. But the potential for taking an off the shelf
componentized application (w/o build-in adaptation strategies) and make
the application server dynamically adapt it. This is so much better.

Different optimizations are possible for different client groups (even 
if their request patterns end up using the same beans) the server may
adapt the application and optimize each request path for each group of 
clients separately. 

You can introduce additional server component at run-time to adapt to
changes in bandwidth or to handle a DoS against the hosted
application. The possibilities are there. Use your imagination.
