Hi Shayne, osgViewer automatically shares a single DatabasePager between Views when the Views share the same scene graph. This is required to avoid inconsistencies in the scene graph causing errors. Sharing a single DatabasePager doesn't prevent that pager from handling multiple viewpoints at the same time, if fact it knows nothing about viewpoints, it only handles database requests for tiles, so it totally agnostic to how you manage your viewpoints. Everything should basically just work out of the box without any need for specific settings from yourself.
There is however and outstanding bug relating to multiple viewpoints causing the pager to not correctly expire subgraphs. There is also an issue with trying to mix the DatabasePager and the Registry caching of models as this disrupts the present expriry scheme. There are couple of recent threads on this, including a proposed fix. I'm awaiting for feedback from the community before I can address the issues, but once we get some good test cases I don't expect the problem to be too hard resolve. Robert.
