While searching for a tool to synchronize file owners and permissions (but not contents), I eventually went for a simple perl script. Basically, I use File::Find to recursivly list the owners and permissions of a directory and STDOUT it. Passing a second parameter to the file will read from that file and show difference. Now I'm considering adding a few extra features (such as actually chmod'ing and chown'ing too). Will be either listed on Sourceforge or CPAN. Updates will follow.
