I have been watching Ubuntu for a little while now. Ubuntu really seems to be an organised open source distro - and is probably the first with a strategy to take the corporate desktop. Between Cannonical (i.e. Mark Shuttleworth, the original founder of Thawte) being behind the Ubuntu project - and due to the way they are working closely with the open source community - Gnome, Debian, Gnu arch etc. - I think this could be the 'organisation' which delivers a 'corporate Linux' to the business world - with revision control, choice of paid or 'community' support etc.
