Indeed.

Just like with TOE, from the net stack's point of view, an iSCSI HBA is 
essentially a wholly asynchronous remote system [with a really fast 
communication bus like PCI Express].

As such, the task becomes updating the net stack such that 
formerly-private resources are now shared with an independent, external 
system...  with all the complexity, additional failure modes, and 
additional security complications that come along with that.
