If you are in Europe and want to hear about libferris and other cool storage stuff (register &) drop by the
NLUUG Spring Conference on Storage on the 7th of May.
I will of course have a maemo unit running libferris there as well as a laptop. Carrying a server with ferris is a bit too much though :) I'm brewing up the slides now with XQuery, KML, and SQLite goodness. Probably not the first three terms you think of when the words Virtual Filesystem are muttered.
