Re: [Phpwiki-talk] On the fly ZIP snapshot.

Hmm. It might be overkill. How long will it take for you to do? I'm
worried that you might spend 100 hours on something that might not have a
great demand... but it would be great to have a secure way to dump a Wiki.

Since this is an admin feature speed is not important; but if I read you
right, you're going to implement zip in PHP?

Is there anything you can't do? :-)
