Won't work.... No way to do this. Against the open source way :-).
Seriousely, if you're using this outside of drupal, you might consider casetracker instead. I started with project, and moved to case tracker for similar reasons. It has this functionality. There's a lot of extra CVS stuff etc in project that gets in the way. Project has a lot of Drupal.org specific stuff in it.

I installed the Project and Project Issue modules yesterday, but it seems I can only assign an issue to myself or nobody. What do I need to do to be able to assign an issue to any user?
