Well, the IIfx has loads of DMA goodies.  Software support of them isn't here,
but I am sure that will be fixed quite quickly as soon as they get sys 7 out
the door (they wouldn't put all that hardware in there for nothing, would
they?).  I would also assume that all future high end macs would have at least
the IIfx's DMA capability - but of course these are my opinions.
