I made a video of searching my iPhone loaded with over 2000 PDFs from MIT’s OpenCourseWare. The search engine, Hyper Estraier, is the same one used on gnu.org but running locally on the iPhone together with a local lighttpd web server. It performs very well and provides a nice way of accessing or iPhone when on your daily commute!
I have updated btlogger to allow various command line options. The software should work on any Linux system with Bluetooth. There is a packaged version for Openmoko:

and a binary for the Nokia Tablet:

An empty database can be dowloaded from here:
I have not had time to look at packaging this but here is a tarball of the build which you can untar in the root directory. It will place everything in /opt/iphone
