@dafyre You should be prepared for plenty of things their that even their $40,000 firewall can't do, unfortunately.
I can tell you that as of 12 months ago on an MX80 its not possible. I have customers that insist we use them but I refuse to sell them.
Meraki started as RoofNet, then they screwed all us original supporters over and started making network hardware. I got on board early on, then the price jacking started along with the hiring of annoying Stanford grad sales reps working their starter job.
If you crave all the network visibility of Meraki just deploy Ubiquiti Unifi on EC2 and enjoy saving 75% off all your hardware purchases. You get great visibility and control and Meraki doesn't own your customer -- you do. The cloud and network monitoring dashboard has AT LEAST feature parity.
