* Component development. Many of the OOTB components require LiveSite, why is that?
* Extending the data model. I appear to be missing some Interwoven packages like com.interwoven.livesite.dom4j.Dom4jUtils and com.interwoven.livesite.dao.DataAccessObject. I presume those would have been added with a LiveSite install? How does not having LiveSite affect using externals?
* Custom layouts for pages and sites. In another thread, someone indicated that LiveSite is required for custom layouts, is that accurate?
