Topic: fireface 400 & tc electronic powercore x8?

Hi,
I currently use a new macbook pro with a firewire 800 port which i connect my fireface 400 into, i am now looking at buying a powercore x8, has anybody got a similar setup?
is it possible to daisy chain the rme and powercore together so they use the same firewire port? Sorry i am not good with technology!! Or will this caue problems with the bus i.e. limitations etc
Any info appreciated, cheers
