Hi there,We are pitching to a client and they've been impressed with what they have seen so far of Umbraco.  They have now asked us to have a think about these following questions:   1. How would we integrate content or data easily from other sources?2. What can an Umbraco solution offer in line with what a SAAS solution offers - in terms of integration and api's – the key here being an ability to plugin but also extend plugins and expose content to other systemsIf anyone has any succint and usefull answers to these questions we'd be very grateful.  Many thanks!
