       find . -perm +o+w -print

...lists all files and directories that have "o+w" permissions.

Do that on both directories - redirecting the results of
each onto a temporary file. Then 'diff' the temporary files,
doing a 'grep' for '<' to get the files that were o+w in the first
directory but not the second and run the output of that to another
temp file.  Now use a text editor (or 'awk' or 'sed' if you know how)
to replace every occurance of '<' with 'chmod -w' and run the
output to a fourth temp file, run that as a shell script and
you're done.

Try doing *THAT* in Windoze!  (I guess you go out and spend $200
on Norton-write-protection-unscrew-up or something)
