* Kurt Seifried:

Firewire has DMA. 

http://cansecwest.com/core05/2005-firewire-cansecwest.swf

eSATA - also does DMA.

Thunderbolt also does DMA. 

In other words a lot of the newer/higher end interfaces all do DMA
which is ... a problem.

Gigabit Ethernet adapters also do DMA.  Is it really the case that the
(e)SATA implementation is as problematic as IEEE 1394?  I don't think
SATA exposes the DMA functionality over the wire.
