Like the Open Software Foundation before it, Unix International Inc may be forced to relinquish its seat on the board of the X/Open Co Ltd because to the cost of membership. Unix International’s ticket runs to some $750,000 a year plus extras which brings the total up to around $1m it must pay annually, the same price point at which the Foundation retired. Unix International, an $11m-a-year affair, wants to retain its input into X/Open, but unless it can come to an arrangement over some other form of membership, something the Foundation has so far failed to secure, it is likely to turn in its cards at the end of the year. Unix International and X/Open were due to meet on the issue last Friday.
