try
http://members.aon.at/neumair/index_en.wml

it doesn't give you the full, shiny WML user experience, but it works. what would happen on a real WML device is that the WML-site comes up automatically when you go to http://members.aon.at/neumair/
also, there'd by a stunningly beautiful black-and-white image on top of the page. (and by black-and-white, i mean real black-and-white: no shades of grey) the plug-in can't handle this image format.
and of course, you wouldn't see all of the text on one page. the sections (properly named cards) would appear as separate pages on your handset. this is why you need the links in between for navigation.

now isn't it beautiful?
