Went through this last week with dnsimple =) The one problem I encountered with cloudflare is that they don't allow you specify none cloudflare NS. This presents a problem if you want to have redundant, cross provider DNS. In our case, we could still specify a cross-provider mix of NS records at our registrar, but it seems like it doesn't take affect until the TTL on the cached NS records expires. So - this left us with a failover, but not really a graceful one.
