I began tinkering recently with a non-relational self-contained binary format for feature data and indices. The toolkit includes Spidermonkey for querying and view generation using Javascript. It's written in C and uses tokyocabinet for storage and libgeos for topology/geometry. The idea was to build a manager on top of this for distributed, eventually-consistent geospatial data storage.
I'd be very interested in talking about alternatives to shapefiles, including the very cursory work I did. The project, called "Grist" is on github: https://github.com/runderwood/grist -R.
