It would be nice if I could just override
the 404 error though.

I just did that using mod_asis. The .asis document can set its own 

headers, including status:

   Status: 200 OK
   Content-Type: image/gif
   Cache-Control: public, max-age=7200
   Expires: Thu, 01 Jan 2009 00:00:00 GMT
   Last-Modified: Sat, 20 Sep 2008 20:32:04 GMT

   GIF89a[dummy image]

This is for an image server where URLs of missing images receive a dummy 

image with status 200.

However, I did not succeed in setting a dynamic Expires: header using 

mod_expires.
