In the interest of truth in advertising: VIMAGE remains an experimental feature, so caution should be exercised. That said, I know of at least one non-trivially sized ISP deploying it in production. I have Bjoern Zeeb, who has contributed significantly to the VIMAGE work, visiting the Computer Laboratory for the next week, speaking of which!

(Is anyone else on the list attending the European LLVM workshop in London on 16 September? I'll wander down to London for the day, as we'll have some posters about our ongoing work, including a temporal assertion system for FreeBSD ("TESLA") and our MIPS64 LLVM back-end work, required to an LLVM-based FreeBSD/MIPS64 working.)
