How about adding to the user preferences the option to just display the skins that have been updated on the day of and since the user's last visit to WinCustomize?
This way, if I was last on WinCustomize on 8/22/02, when I go to the WindowBlinds section, I'll only see files that have been updated on 8/22, 8/23, and today.
It should help with bandwidth since it will only display a few skins in each section and won't require the user to manually specify how many skins to display on each page (which, if you only want to see what's new, is uaually too many).
