 Performer MP model is based on an efficient shared memory support from
 the Hardware (aka arena). There is no way to get real-time performances
 across networks, distributed models works well for non real-time applications
 not for Performer.

 We now have an answer to that extensibility problem: the Origin/Onyx2
 platform that have a specific piece of Hardware (Cray Link) that let
 you connect two computers and have a shared memory as efficient as if
 all CPU's were in the same (SGI) Box.

 Note that this is a 'super-computer' technology that is not
 available on PC platforms.
