Excellent point. Some of the app code is terrible. I am hoping we'll prove that we can "go native" and do as well as or better than the existing apps. At the same time, having just gotten badly burned on Clustermatic because people wanted to run xemacs on compute nodes and got unhappy when we said no, I've gotten sensitized to the "wants" of users. How you respond to stupid demands can make or break your project. It's hard to take but we're a service industry. ron
