Of course, I am not a lawyer, but at least in the United States, courts 
have repeatedly held that API's for a commercial software product cannot 
be held to be "confidential", and that writing your own code to 
interface to those API's is legal.  Thus Samba for connecting to 
windows-style file shares.  As such, an open source connector to the DTN 
API would likely violate no law in the United States.
