every time. Couchdb itself recommends pull replication over push. This however leads to another
problem that you have to log in to your target DB instances to trigger pull(or use curl to
specify source and target urls). I think the problem starts when you try to specify a URL
instead of just DB name in the target body.

Yes, these problems are well known. There's been lots of work going into the replication APIs
for the next release. 

You might try trunk and see if it's better for you.

And Damien is working on a brand new replicator, which should be much simpler code, so for
1.1 or some future release we'll have licked this stuff for good.
