Re: Problem with multiple sites and crossposting

We have local newsgroups in which we want the posts to be immediately
visible, but since we want the other site to receive them too - we
just synchronize every two hours.

I'll need to try that.  We are using SSH to both encrypt and compress
the traffic.

Looking at the path line, it looks something like this:

Path: A|B|A|B|A|B|A|B|A|B|A|B|A|B

I can't claim much expertise in the sources at the moment, so should I
just wrap snstore in a shell script that greps for 'Path' and hostname
and rejects the article?

Though if I understand correctly, that article will then be
transported at each synchronization point anyway, until it expires
(which in our case will mean about a year), getting rejected at the
other end, using bandwidth each time, correct?
