Demon internet used this, and I think maybe still do: http://echannel.www.demon.net/helpdesk/technicallibrary/sdu/... Funnily the images on the page actually show that they are using an evaluation copy!
I've sent them an email referencing this story to see if they step up and at least make a donation.
Would be great if some more people could email them as I don't see them taking a random email like I've sent seriously.
EDIT: Demon internet is an ISP based in the UK.
