It's great to be able to access Hitchwiki information when you're not connected to the internet. There are several options for that.

DICT
Guaka converted the Hitchwiki database dump into the dict format. If your OS is Debianic you can try to apt-get install dictd and copy this file into /usr/share/dictd
I'm using this on my Nokia 770 myself, so I can access Hitchwiki info while on the road!
