no problem, i always introduce bugs together with features. :P

i can provide some interesting logs. :P i just finish a test that see a
10TB device via MS iSCSI ini. hope via linux soon. also some scsi cdrom
traffic traces.
for protocol description, hehe, many people are better than me on that.
in fact, what i want to do is to add more scsi commands support in
ethereal. for example, now i debug the >2Tb device support, the
read_capcacity_16 is unsupported. and many others. the only thing i lack
is the time. :P last july i am free, so i can improve the isns support a
little bit when i code my own isns client.
hehe, stop blah blah.
