cloud-init for BCE under VirtualBox?

[Greg MERRITT]

I've become seriously addicted to using #cloud-config in AWS to reproducibly customize images through Ubuntu cloud-init.

I'm interested in doing similarly for BCE under VirtualBox. I did a bit of Googling, and came up with this:

Still scratching my head a little bit over this example -- I'll have to try to walk through -- but have others used cloud-init to customize their VirtualBox BCE? Any pointers?

Thanks!
