Hi Dan,
Your approach also seems good. Only thing here is we need a solution that can do this. If my HDD too can be connected to TV and can be accessed as a network drive on all other devices the deal is done. I believe we are looking for either of one option from below
1. Have a file generic explorer on WebOS that can allow access to network drives (Most preferred)
2. Expose storages connected to WebOS so that other devices can access the files over network.
