Looks like the folks at SCO have some backpedaling to do. Note in particular, the comments made by Novell CEO Jack Messman in his last paragraph to SCO:
" We, like others, are concerned about the direction of SCO's campaign. For now, we demand that SCO either promptly state its Linux infringement allegations with specificity or recant the accusation made in your letter. Further, we demand that SCO retract its false and unsupported assertions of ownership in UNIX patents and copyrights or provide us with conclusive information regarding SCO's ownership claims. In the future, we hope SCO will adhere to standards of strict accuracy when stating its rights in UNIX."
