Hi.
I've just stumbled upon Ajenti and thought it worth a post here.
It seems to be a lightweight webgui / admin panel, it's a python based and no lamp needed so this might be the perfect companion to our Arm devices.
A little confession,
I'm a long time windows user and my previous attempt with Linux was Ubuntu and I absolutely hated it (purple, yuck).
Arch Linux Arm pushed me to install Arch Linux on my main laptop also.
I got so used to the terminal, ssh, scp (thanks to gnome's drop down terminal extension) that I really don't know why one would want a webgui.
Anyway this looks like nice solution for an alarm webgui.
