It's great to be able to access Hitchwiki information when you're not connected to the internet. There are several options for that.
httrack
"HTTrack is a free (GPL, libre/free software) and easy-to-use offline browser utility."
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
Guaka is using this on his Nokia 770, so he can access Hitchwiki info while on the road!
You can download it at: http://groups.google.com/group/hitchwiki/web/dict-hitchwiki.tar.bz2
Hitchzine
The print zine that Zac is working on (seriously, I am working on it).
