I guess you have lots of whitespace:-)

Yes, but it's part of something bigger, and not published.

Actually it'll gain a lot less than you'd think, because once you've
stripped down the whitespace, the compression you get by gzipping it
will be correspondingly less.

As an alternative - yes, it's a possibility.

Actually the server overhead could be pretty negligible: certainly less
than gzipping it.

If you take a simplistic approach (and don't mind screwing up <PRE>), the
module would be maybe an hours work.  You could perhaps take mod_txt as a
startingpoint for manipulation like this.

Alternatively, grease my palm and I'll write it for you:-)
