I don't think we should over-regulate things but technically, strictly, legally speaking if you run osm2pgsql on the planet file you have already created a derivative dataset. If you then use this to serve map images to the public, the license could be used to force you to provide the contents of your pgsql data base to the public. You might be running a version of osm2pgsl that imports minutely diffs into your database. Providing minutely dumps of your database would however be impractical (creating them takes more than a minute). So your only avenue would be to grant public read access to your psql database, right? (Which of course is a security and performance nightmare, you can bring down any Postgres server with an evil query.) This would also be true for our own psql database that sits behind the Mapnik rendering - a very strict reading of the current license draft would require you to make some sort of SQL dump available, I guess - it is probably not enough to simply say "I used the planet dump and processed it with osm2pgsql". (Note that I'm playing advocatus diaboli here, it's not that I *want* this to be the case, I'm just looking for ways the proposed license could backfire!) Maybe the license needs some provision that says you *either* have to make your derived database public *or* provide documentation that explains how you created the database using publicly available tools from publicly available sources. In that case, the aforementioned map provider could just say: "The map you see here is based on OSM data processed by osm2pgsql with daily patches applied", rather than having to make available a full dump or grant people read access to his RDBMS. Another thing we could do is put in a provision that says if your data is permanently updated, it is sufficient to provide regular snapshots to the public instead of the live thing.
