I’ve been playing with Project-Fifo at home ( http://project-fifo.net/ )
and wrote a very rough knife plugin in a morning -
https://github.com/bakins/knife-fifo depends on
https://github.com/bakins/project-fifo-ruby
Not sure if anyone else is playing with project-fifo, but its been awesome
for playing with smartos. Knife plugin is very early and full of bugs and
missing lots of features, but wanted to get something out there. Be
gentle, I’m an old school C guy 
As always, patches welcome.
