I believe one way is to set up site A as a master site.  Site A gets
all incomming feeds and in turn is the only site to feed site B.  Site
B would then get all the articles in the same order that site A gets
them.  The only drawbacks are 1) posting would not be allowed on site
B.  2) no new incomming news would be received when site A is down.
