Now I'm on OSX, and I suppose I should install some protective somethingorother, just to be on the safe side...
If the users are actually installing and running programs, those programs could easily contain malicious code to delete users files, and maybe send spam, etc.
At least make sure your users never enter administrator passwords at the request of anything the download.
A while ago, there was a weakness revealed that one type of file (e.g., a script that sends your files to a remote location) might masquerade as a file of another type (e.g., a Britney video) but this was patched soon after the exploit (the much ballyhooed "Mac OS X Trojan Horse) was brought to light.
