I haven't tested it, but I will say I'm very interested in this
functionality.  In past projects we've had to write our own little
viewhelpers so we could distinguish between "positive" and "negative" flash
messages, so this sounds like an appropriate solution.  From reading, it
sounds good :)

Just my thoughts,
