Well, it's not that trivial than just an ro string file.
But not that hard as I first suspected :)

I've introduced a few new helpers for rw integers, which works
quite similar to the ro string stuff, but with anouther handler type.

I'll post a patch in the new testers list.

The next step is actually changing the uid. Can I just write 
new values to the uid field(s) in the task struct or is there
something tricky about that ?
