The three first are the most recognized brands for content management software, at least among industry journalists. For anyone previously involved with content management of a large scale site, Interwoven's, Broadvision's and Vignette's high-end suites, respectively, are probably the default chooses for web and e-business management, no questions asked. I'm reflecting this because I would like to have the big picture of what each product is able to do, without exagerations. I've never seen running any of those products, and since I must advice the company I work for about the software it will need for its news portal, in adition to what nice pdfs and catalogs can show off, I am truly interested about what Zope can do and what it can't, COMPARED to those first. Is Zope stable enough working connected to large databases? How does it behave with high traffic sites? Does it support clustering? What is the largest site running it? Have anyone put their hands on any of the mentioned tools and make comparisons? Although it sounds silly, I need reasons to convince someone else that saving money is for good. That none of those super-coded-worth-a-third-million solutions is much better that a genuine GNU initiative, meaning Zope in this particular case. And, by the way, when are we going to see the first large ASP (meaning NASDAQ registered) with support for Zope? Thanks in advance, Ausum
