I have dreams of implementing Diff/Patch in full PHP, and have
even investigated the algorithms required, but I don't have a
good feel or expectation for when I might actually have an implementation
ready.  I know it's a pain for people stuck on webservers that don't 
have diff(1) and patch(1) conveniently available, but a built-in diff/patch
just hasn't bubbled up to the top of my work priorities yet.

I wonder how other PHP-based wikis handle their page revisions/restores?  
Do they make use of the external programs also or do they have their own 
implementation?
