Okay sounds good.  In fact, would you mind deleting it (and any others
we don't need?)  If by some weird chance we happen to need them, we can
always pull them out of the cvs history.

It's true that the permissions are ignored by php.  Kees verified that.

I investigated how to disable php on a per-directory basis and found
some apache configury to do it.  Unfortunately I wasn't able to get this
done via an .htaccess file.  I've sent in a bug to the fdo folks to add
this to the apache config for our incoming dir, but haven't heard if
they've implemented it yet.

Great to hear!
