In reply to zakmacro:
Andy K's website in general for big wall and soloing stuff. Plenty of good articles to trawl through. He's also running big wall courses in London at the moment.
As for European big walling, unless I'm mistaken, you choice is either Troll Wall (has repelled/killed/paralysed an army of climbers over the years, including Andy K) or a handful of properly nails routes in the alps.
