Lightroom :: Publishing To Dropbox On Two Separate Machine?

I have a bit of a unique setup which isn't quite new and isn't the issue. I have a LR 4 catalog (catalog settings) and collection of images in Dropbox that i use to do some small work between a desktop PC and PC laptop. Works fine on a  good connection as long as i avoid conflicts. That's not the issue. I'm wondering if their is a solution to using publishing services in the catalog on both computer. The problem i am running into is that the destination path for each publishing service (in this case they are publishing to another folder in Dropbox to upload to someone) is unique to the machine that it was created on. So if I created the publishing service on one machine it can't be used the publish if I'm updating it on the other computer because the paths to the files are not relative.
 
The only solutions I can think of are:
 
Have the paths on both computers be exactly the same, which means updating the user account names to match on both machines.Setting up separate publishing services to the same folder for each computer (an annoying solution).Look into a dropbox plugin which i haven't done yet.
 
While I am at it, any add on to prioritize the LR catalog file to be the first file to sync over the connection or LAN once it closes. This would certainly work with occasional conflict file.
