Thanks for your comments. I've revised the document to clear up a few
things you mentioned. Terms such as 'security features' and 'secure
features' are well known in software security literature, but I've tried
to elaborate a little.

I also didn't want to *dictate* exactly how the project implemented
security and that now comes across as vague :)

That's not the case. I've improved this section. Please see if it's
clearer now.

That's because it varies for httpd, svnserve and sshd and the (security)
people I showed this to before mailing it to the list understood exactly
what I meant. I've tried to elaborate on this in the document, too.

I much prefer 'facts' or 'observations' to accusations. In some of the
other responses, a few problems in my data have been pointed out, so
I'll revise that as I respond to each post.

I prefer the dark of the night, after midnight and before four-thirty,
when it's more bare, more hollow.                http://a.mongers.org
