Users not particularly experienced in database-administration should NOT attempt the following.
Has anybody thought about hosting the data-dump on their own public-facing server, and allowing queries to be ran against it by visitors? Likely smart to put a cap on the query-execution-time to keep somebody from trying to smash your server. Would be smart to have it in its own database, with its own user-account too. Limiting the account to read-only queries is necessary as well.
Any thoughts on this?
Update: I'm currently working on getting all of this data into a MySQL database. Going to play with the idea locally, and maybe attempt to host the toy.
