This is how easy it is to get lax to run on your linux machine :

hg clone http://www.logilab.org/hg/lax/
wget http://googleappengine.googlecode.com/files/google_appengine_1.0.2.zip
unzip google_appengine_1.0.2.zip
./google_appengine/dev_appserver.py lax/skel/

Point your favorite browser to http://localhost:8080/

UPDATE: LAX is now included in the CubicWeb semantic web framework.
