As I understand it, you can set the timestamps to svn's "Last Changed
Date" using "use-commit-times". That way consistent timestamps will be
used across all workspaces on all web servers in the server farm.
And no, 3rd party apps would have to be Subversion aware to take
advantage of things like 'svn status', etc.

In a workspace, yes. If the files are deployed outside of a workspace,
you will need a tool to do so. IIRC, one version of tar will actually
compare the files in the tar with the externally deployed files.
A poor man's audit tool:
find . | xargs cksum | perl -ne 'chomp; @a=split(/ /, $_, 3);
print qq($a[2],$a[0],$a[1]\n);' | sort > master.txt
chmod 444 master.txt
Put the command in cron save the output as audit.txt.
diff master.txt audit.txt > diff.txt
email the results.

Eh?
