I made some recommendations directly to the Autodesk Seek Senior Product Manager late last year about a local LAN version, and reflected the general idea here on AUGI.

While I don't expect my generalised ideas to be a final solution, hopefully they sparked some internal conversations about the concept. For a product such as Revit that relies heavily on locally created content is really needs a more informative way to browse it, and I think a simple Seek alternative would be great.
