Unclear how iSCSI will be able to determine whether the target is local or 
not given IP subnets can already span large geographic distances and the 
movement to 10 GbE translates to large Ethernet fabrics.  Also as 
transparent fail-over is delivered by multiple vendors, what started out as 
local may become remote in some way.

I strongly disagree with making CRC protection optional and I suspect 
customers will given the various studies on error rate escapes associated 
with TCP checksum already discussed on this reflector.
