Code review comment for lp:~tim-simpson/nova/multiple-notifiers

Tim,

    That's actually *exactly* the reason I moved that kind of functionality external to Nova. I believe we should be focused on developing the minimum amount of functionality inside of Nova because anything else interferes with the core competency of virtualization.
    I'm afraid things like this ending up in the code open up the floodgate for people to create insanely complex notification systems. I also wanted Nova to have an "indifferent" attitude to notifying end users. I believe this allows Nova to send notification as quickly as possible in as non-specific a way as I could muster.
    With that said, I'm not actually worried so much about *this* particular patch. Because this is more of a philosophical argument than one pertaining to the functionality around this patch, I'm going to abstain. I'll have Dragon take a look.
