How long did it take you?
it can't i suppose, because if you want to read or write the network mapped drivers, it will still download to your local first, like you can't edit file in the network mapped drivers directly,,if you can use the network mapped drives like local hdd,,,than who will by the hdd...just apply lots network mapped drives!
i have my miner running on a network mapped drive. i'm using one of my spare 4tb ext4 formatted disk in my qnap whose shared folder i have as a mounted drive on my windows 8.1 machine and i've found 4 blocks with it so far.
it's still going. it's a tad below 600GB and taken 1.5 days to get to this point. still lots more to do as i set the range from 0 - 8192000 and it's only onto 2316000 at the moment.
