LG sent me some documentation for their new 2 bay NAS devices, the N2R1 (DVD) and N2B1 (Blu-ray). These two devices not only let you backup and share optical drives, you can play back DVD's and, in the case of the N2B1, Blu-ray movies over the network. I was a little stumped at how they were pulling this off until I saw that they support iSCSI for optical drives.
For those not familiar with iSCSI, this means that a computer can mount the drive in the NAS over the network and, for all intents and purposes, treats it like one that is installed locally. My only concern here is bandwidth when using its wireless connection. LG's new NAS devices support 802.11g which, under ideal conditions, is fine for DVD's. For Blu-ray though, I don't think its going to cut it. I came across an article (http://www.linux-iscsi.org/index.php/ISCSI/HD) stating that iSCSI/HD maxes out draft 802.11n hardware.
Has anyone done this? Is it even feasible? I guess I'll find out soon.
