I've been reading silently this thread until now. Well, I don't want to contribute to flames, so please consider my opinions just as humble wishes.
In case you are curious, I'm using pfSense on my company. We have just started to make pfSense installations to our own clients. Speaking for myself, I also like m0n0wall theme far more than pfSense's one, but the theme I would really prefer is a clean, XHTML & CSS validated theme, and it would be very valuable for us at least WAI-AA conformance on the user interface. Yes, I know making a theme like this does take a great deal of work and time; I would prefer to have less features and WAI-AA conformance, but I think this is not the common feeling, so I don't have too much hope for my wishes ;-)
