Are you under the impression that eSATA doesn't have DMA? Seriously, DMA is the only way to have high-performance data transfers on any computer architecture, which is why any bus designed for performance supports it. DMA is a security hole, definitely, but until most PCs start shipping with IOMMUs that's just something you have to live with. Physical access to a machine typically leads to all sorts of possible exploits...

Not really - heaps of PC motherboards have Firewire. Both my computers (a cheapie and an expensive one) have Firewire ports.
Firewire is a bit of a white elephant. For ordinary consumer-level devices there's USB. For ultra-fast external hard disks there's eSATA. Firewire is the domain of Mini-DV-camera owners, kernel programmers, and black hats.
Typical Apple BTW - encouraging a standard with a showstopper security problem.
