Amiga with 3 CPUs?

[scholle]

Owning a CyberstormPPC Card with a 604e and a 68060 processor, would it be possible to use a third one (SharkPPC with Mediator) together with them under AmigaOS 4.x? I'd like the idea of doing the fast G3/G4 most of the work while coding mp3s in the background with the old PPC. Or calculating fractals or...?
Or is the speed gain of the biggest CPU so big that this makes no sense?

O.K. the use of such an arrangement may not be so big; I see it mainly from an "Only Amiga makes it possible" point of view. :-)
