Assuming you wish to have a solid message-passing infrastructure between disparate systems, is there an "open-systems" approach to this functionality? The article mentioned the proprietary nature of MQSeries, which is true, but it did not mention how the functionality would be duplicated without it. If it could be duplicated without MQSeries, then wouldn't WebSphere also play in that arena? This sounds more like marketing than a technical discussion. I particularly liked the subtitle "It won't operate with other systems, says maker of other system...". This may be like Microsoft accusing other vendors of being proprietary.
