Yes, but you can use ghost to do multiple machines at one time, I used to do 8 at a time but only cause that's the most that would fit on my server rack
I really don't understand this whole lockdown hack issue. The hack isn't what is illegal, and I think it's wrong for the mods to auto-assume that the majority of peeps would use this for piracy, but it's your choice of course as the writers. I really doubt though that you are preventing ANY piracy by not writing this hack as they aren't going to stop simply because of the lack of this hack.
