...for the expert. PHP is rather new to me, usually I handle bits and
bytes and machine cycles in _small_ embedded stuff.

Patrick Michaud already mentioned this.

PhpWiki uses the multipart mime technique at least in it's dump

It looks cleaner, but maybe it's mode expensive. I'm not sure.

To guarantee a "unique" separator, one had to check for collisions
with the page text.

You know the Firefox issue with the message delimiter? Well,
"--Message-Boundary-31415926537" is rather unlikely to be in the page
text compared to "From" used in the mbox format. And they simply got
the escaping wrong.
