For many years I have run the primary Redhat Mirror server in New Zealand, about seven years ago I registered redhat.co.nz (ftp.redhat.co.nz still works) and this is what most people used to access the site (that is what was listed on the Redhat mirror list on their website). about 3 years ago all of a sudden Redhat started jumping up and down saying that (understandably) I couldn't use their trademark so I changed it to something else. They were really quite nice about it in a gruff sort of way (ok, they gave me tshirts and hats) and I haven't heard from them since. I would not assume because they want to make sure they are the only ones authorising the use of their trademarks that they have any more sinister intentions.
