Great. I couldn't tell from the wiki page if doing a:

  POST /_replicate?source=$source_database&target=$target_database

Would trigger a one way or two way replication. Sounds like you're 
saying its one way, which is exactly what I need.

Maybe I can figure out some manual process of GETting and PUTting, 
though I suppose this would render the builtin _id and _rev bits worthless.

Thanks for the feedback. I appreciate it!

Before I can submit any patches, I'll have to learn Erlang.
