You could also test my PHP implementation of diff and patch. There's a 
link on

http://www.pmichaud.com/wiki/Development/PHPBasedDiffEngine

The thing with the current version is: It is quite memory hungry. 
However that applies mostly for big pages. I've ran some tests, and it 
was not able to diff a 2500 line page
where 100 lines were deleted without running out of memory.
With pages of only hundred of lines, it worked fine most of the times.

Also, I haven't done a lot of testing to see, whether diff and patch are 
consistent.
In my tests, they worked so far, but you never know.
Now, this is all experimental. If you want to try, I'd be happy to 
assist you.

Same for all the safe mode folks out there!
That brings me to a question I wanted to ask all you PmWiki-users out 
there.
What is the maximum number of lines that you have in one wiki? I just 
want to know,
how efficient the algorithm has to be to give it to people without a bad 
conscience.
