Lite version for mobile and low-speed connections

Hi all, this is really for BugHunter and the other administrative gods... Accessing the site over my phone using 3G over the las week or so has been painful. I have a feeling the number of images might be degrading the experience. Would it be fair to request perhaps a lite version of the site which is enabled via a button on the homepage for those who have a crappy internet connection. Also perhaps it could be the default for those accessing from a mobile device. I have a sneaky feeling the background image is the main cause, so maybe a css file version without the background image is an option - it could be default for mobile media types, and/or if end-users have the option to turn off the richness that would be cool. Anyway just a thought - and thanks for this place!
