To potentially get it added to the UTM: UTM Application Pattern Requests: Hot (86 ideas). There would need to be something added to the header/requests that would identify the browser specifically for this to be possible.
Looks like it's not a PC based thing, it's a mobile app for ipad, iphone, and android devices.
It is in essence an app that remotely controls a browser spun up on demand in Puffins data center. (a proxy on steroids?)
This is meant to speed up the mobile browser (and allow Flash) but effectively bypasses all rules.
I am guessing just tracking the ips that are used for Puffin servers would accomplish this. However, adding "Anonymizers" and "Anonymizing Utilities" does not work.
