Older/cheaper TP-Link products allow the connected FTP drive to have separate "read" and "write" accounts. I can open up the device to allow Internet access... and only give friends/family the "read"...

@Timuk Many of the cheaper TP-Link devices allow multiple FTP accounts. But if you buy the much more expensive devices... they *REMOVED* that feature. Needless to say... I'll never buy another...
