nope, but it could be something like it.

Look- it's just a really simple junction box to add "soft" hardware to a 
SIM.

I used it to help sort out some race conditions in configuration, and 
I'm now using it to flesh out the REPORT LUNS implementation. It's a lot 
quicker to load a kernel module that creates ~10 or so random luns 
between 0 and 1024 then it is to fart around with various GUIs to set up 
real (and scarce and hard to share) hardware. In fact, it's even easier 
to do this than it is to set up target mode, because you can do this on 
a box that doesn't actually even have any SCSI hardware.
