Are there any web interfaces out there for DHCP servers that accommodate management of DHCP option 82 configs? Neither webmin nor Glass seem to handle ISC's agent.circuit-id outside of presenting the raw config file. I can do that just fine in nano, but I'm looking at something more user-friendly so I'm not the only one that can work on it.

I'm also cheap, so not looking at Infoblox or anything like that.
