Remailers on networks like Fido or WWIV

I've seen a lot about remailers on Internet but has anyone done any work with remailers on Fidonet, or WWIVNet style networks? I've been thinking about a WWIVNet anonymous remailer and can easily implement one for email, but the public postings would be much harder although I do have some ideas on that. If anyone else out there has any ideas, or has started on this already I'd really like to hear about it. d. saint
