Code review comment for lp:~vladimir.p/nova/vsa

I'm of the opinion that this is much better than the previous version (thank you for that!) and that we should approve this and then decide on it getting in to Essex or Diablo.

So basically, I'm approving this for trunk, but you'll have to get a FFE from ttx to get this into Diablo if I remember correctly.

Thanks for your hard work on this.
