Is it possible to use Drupal to feed a few dynamic portions of a mostly static website? We have a plain old website and are looking to create a sibling site just for web-app stuff (private CMS, databasing, some forms for specific things, etc.). Some of the content we create on the sibling site (which would be Drupal), we'd like to render in areas on the primary site (non-Drupal). An example might be a news feed generator that displays on the primary site, but is actually fed from content created in the secondary site's interface. Another potential workflow might be a Drupal installation that's located in a subdirectory of a mostly static website. A general login link could redirect users to the drupal area, but could we get any of the content they create outside of that, modularly, so we can keep our nice rigid site design? I guess I'm looking to harness Drupal as more of a framework than a CMS.
Is any of this possible? Is this even a logical concept, or am I stupid for asking?
Thanks for any suggestions.
