As an alternative to changing the permissions on the live file, if you 
don't need up to the second accuracy, you could just make a cronjob that 
runs every minute as root and copies the file someplace friendlier and 
makes it owned by apache.

If you do need up to the second accuracy, you could write a script that 
could run and check the file every second or something.  Wouldn't be too
