In order for two systems to have block-level-access to the same disk a 
consistency management layer is required that does not in general exist. 
apart from that, yes.

block-level-filesystem managers are common enough in san applications, and 
apple actually sells one (xsan) but none of the firewire stuff leverages 
that.
