Incomplete thought: to a first approximation it shouldn't really affect you much at all. Most of the 'driver' changes are things just put into slightly different structures and called something a bit different. The notion then would be to start taking this further and doing more and more useful things with it. For example, camlib/camcontrol would then be taught about the different transport types and could report WWPNs and whatnot for FC and whatever that ridiculous 511 byte UUID there is for iSCSI. Everyone I know who uses FreeBSD with Fibre Channel and target mode has to hack things to get that information.
