Hi Takahashi,

looking the SAMBA docs[1] i realized that remote browse sync
means that an LMB will sync its browse list with another
LMB. Thus this "trick" will allow two LMBs to find out
the lists of each other. There is no DMB mentioned in
this process.
Btw how did you examine it? Did you setup a test lab
that implements the setup as i described it?
