Password protect comments file

[MaddMatt]

I didn't see any mention of a password protection for the comments xml file. I'm currently using the previous version, and constantly get spam in the comments file. I've tried moving and renaming it from the defaults location and name, and still they bypass the manual entry and post long viagra links over and over again. I added a password for entering info, and it works for typing in from the photos page. But, the spammers don't go thru the normal way, and go directly to the xml file. So, a password protection to write to the comments.xml file would be greatly useful..

Thanks.
Matt.
