Hi Lars,
though I definitly like your idea, I'm strongly in favour of coordination and maybe even get it driven by the EB/TAB. Write up some official statement, link it to a comparison page which has a list of all companies willing to install dotLRN for these institutions. And send this official statement to the WebCT customers as well as the IT-Media. I will happily help in this effort but need to know a little bit more about WebCT to draft the letters.
Get it moving !
