My advice would be "Figure out how to deal with the fact that these are not going to happen". If you are distributing data that people care about altering, modifying, etc. then there is no practical way to prevent them from doing so. A license agreement of some kind can keep 'honest people honest', but no means, technical or otherwise, will prevent people from distributing data that they want to distribute. Additionally, these types of restrictions typically serve to limit the usefulness of the data -- the more restricted a dataset is, the more likely you are to block legitimate usage unintentionally while 'protecting' the data. That said, the last restriction is well-addressed by Creative Commons licenses.
