If there's a chance a file is modified on both sides the same day, it  
can't work. Merging & conflict resolving like done in source code  
management (usually) isn't an option for binary files.

So you have to make each file/directory/project read-only on one of  
both sides and stick to one-way syncing.

Another approach could be the Andrew File System AFS. It's designed  
to solve problems similar you yours: Distribute storage over network  
nodes with slow or interrupted networks in mind.
