Sorry to drag this on a bit more...

The move from F15 to F16 {u,g}id will work without problems, I think. I 
may have been a bit unclear about installing F16 in a separate partition 
set, while keeping F15 as well in its old partition set, both having 
access to the same files in a common partition set. While I think that 
the move from the old to the new uid/gid numbers will work for F16 and 
access to user files in F15, my uncertainty revolves around whether 
there are other things that could be a problem when changing the uid/gid 
for an existing account in F15, e.g. files in /etc or other places that 
might need to be modified as well. (I know /etc is not supposed to hold 
user specific info; just using it as an example).
