Before spending much time or energy worrying about these hypothetical 
devices, what are the design goals of iSCSI?

Is one of its important goals support for crusty devices which may or may 
not exist? Are we trying to enable support, over IP, for exceptions to the 
rule?

Or is iSCSI focused on a different goal, that of efficient, 
high-performance connection to mass storage devices (both disk and tape)?

It's not as if iSCSI will be exclusively tailored to mass storage, but one 
has to ask "Why is iSCSI a hot topic today?" For the sake of some 
unidentified "odd devices"?
