Unfortunatily they are windows systems. The broadcast software we use
only comes in that flavor otherwise they would be nix.

So when windows objects to an open file being sync'd will rsync simply
skip it and keep going? Or will it bail out of the sync? I can stand
missing an open file since the sync runs every hour.
