One-way Folder Sync App for OSX (for Dropbox and OneDrive)

Now that I'm starting to use OneDrive because MS Office is available for iPad, I need to rethink my workflow, because previously I was putting everything in Dropbox. Would there be a way on my Mac to have an App that would constantly sync my OneDrive (I'd create a Dropbox folder in there) to my Dropbox?

This would basically allow me to have access to my Dropbox folder through OneDrive... provided that my MacBook has synced those folders. Thoughts?

 

I don't think that will do it. I'm looking for a service that will copy and sync all Office files in my Dropbox over to OneDrive. That service looks like it simply gives you one login between all your cloud services.

 

I've never seen this before... very interesting...
