A neat idea, but the resultant vendor lock-in here worries me. I've heard horror stories of the amount of effort required to move away from PaaS platforms like Heroku (I believe Genius is one such tale) due to architecture-specific components like jobs, but this seems to take that reliance to a whole new, all-inconclusive level.

This might be neat or a quick weekend or hackathon project where you just want to Get Shit Done, but I can't imagine anyone ever committing fully to the platform and having no second thoughts.

An open architecture built on this sort of idea would be nifty, but tools like Docker have almost reduced the sysadmin components for a lot of simple projects to something that's not too far from this anyhow, from an ease of use perspective.
