Secure Web Control of Allstar nodes

Hello to everyone,
Just wondering if a secure web-based admin tool exists for our Allstar nodes? Working with a group that wants to use Asterisk/Allstar for a multi-state network, and desire the ability to log in to remotely control the individual nodes. If nothing exists, I'd be willing to write something in Apache/PHP that would simply call macros or control commands (via the asterisk -rx <cmd> feature).
  If this is a bad idea, or better served by sending codes to remote nodes, please let me know.

Thanks,
Tony
