One of the companies involved in what can only be described as the latest round of unity talks among the warring Unix camps, which appear to be being sponsored by Unix International Inc, says that for all the fear, uncertainty and doubt unleashed by Microsoft Corp with Windows NT, the initiative still lacks the compulsion that galvanised the part of the industry – led by those that saw Unix primarily as a threat – to form the Open Software Foundation five years ago. It needs that extra-special final stimulus. The anonymous firm says one of the points at issue in the talks is support of Unix System V.4 ES/MP. What it believes is needed is leadership from SunSoft Inc throwing its weight behind ES/MP.
