You mentioned you weren't intending to provide access to the code, but how about the code that looks at the source IP / password requirement part?
I'm one of those guys who still hasn't fully wrapped their head around PHP yet, so I'd like to see how you did that part.
On that topic, maybe we should have a place/repository on the amprnet to put ham specific software.
A while back I posted a link to a web based rig control application I was running. It uses hamlib for backend and php for a front end. Here is more info:

As for the ARDC director position discussions, my thought is we need more people working on finishing the portal first. I am sure Chris would appreciate that.
