Funnily enough I'm working on some tools which can analyze systems
without needing to log in (by examining kernel memory directly).
Primarily for virtualized systems of course, but I was thinking about
whether these techniques could be applied to baremetal systems too,
perhaps by using some sort of modified NIC BIOS to snoop memory.
