You are right, the danger is there. It's up to everyone to reduce the power of the special forms - here [lambda, def, if, let, quote, macro, style, script, require] - depending on the level of security required for the wiki. A good compromise between unlimited document creation and secure document sharing. Same thing concerning the choice of server or client for page calculation, personally I like the idea of offloading the former and loading the latter, the server being only a remote neutral storage. And you can instal the server inside your computer, it becomes a local application, you will be able to share dumbs file if you want.
