Would love to - couldn't find your email in your profile tho.
To keep the UI simple, I'd like to specify a URL and specify the IP range(s) that are allowed to access each. Bonus points if I can in addition to web UI submit and change the map programmatically. The first allows for greater security for admin pages and similar internal uses. The second allows us to provision for our enterprise users dynamically, who are at well known IPs.
