I would like a complete different system. First I want as much data (actually the complete Wikipedia) as possible. On the other hand I want to save bandwidth. I suggest we have a base version and different modules you can additionally install. Moreover there is a strong need for a full-version. The important thing is, that every version has a release number and you can automatically update/patch your local version to the most current Wikipedia version. This way you only copy the changes instead of download and install every 6 month the most recent Full-Wikipedia distribution. What do you think?
