Mashups aren't just browser-based integration, but can be server-side too. See my recap of the different mashup styles . link »
However, though mashups are technically easy to create and generate somewhat useful Web applications, it's a technology solution that may currently be ahead of a real business problem to solve. At least on the Web that is. Monetization and building workable business models around mashups is something of a struggle, particularly when many of the API and widgets suppliers are currently unwilling to provide much in the way of Service Level Agreements that would make it possible to safely rely on a supplier. Some content suppliers (notably Yahoo!) even have draconian daily metering restrictions while they figure out if competing sites will sprout up and take way their users by leveraging Yahoo!'s own services. So while mashups are a very interesting technical solution on the Web, there's still some work to do before successful businesses can be build around this model. link »
The motivations for mashups are quite different inside of organizations, where application backlogs and demand for more software that will improve collaboration and productivity are often rampant. If this state of affairs is true, far from having too much software, most enterprises don't have enough to satisfy demand, despite the prevalence of mountains of existing enterprise systems, many of which are underutilized. The arguments for letting users self-service themselves with end-user application tools and getting IT out of the critical path for the backlog of simpler applications are extensive and I won't belabor them long here. link »

To see exactly how end-user generated enterprise mashups work, I prepared a screencast that walks through the process of building a so-called "situational application" on-the-fly in a just a few minutes, complete with geolocation and database support. link »
一開始也是在談Mashup的問題就是提供元件的來源及開放性不夠好,在企業內既有的系統也沒辦法提供這樣的特性。
更重要的是,這裡(http://hinchcliffeandcompany.com/screencasts/qedwiki.html)有一段錄製好的QEDwiki的操作,我們可以看到如何很容易就混搭出一個網頁功能。(在3分鐘開始開一個新網頁、6分鐘時新建一個地址清單元件、8分鐘把Google Map元件也拖曳進來,然後將地址與地圖做連結應用,一個可以管理地址並搭配地圖的功能網頁就產出了。)
