It would be very cool to see a working prototype of any of storage coins. Would be more than happy to give them my BTC then. Don't really want to accuse anyone of anything, developers might have the best intentions, it just can happen that the idea is technically too hard to realize.
You try out Metadisk right now, just go the to
http://storjtalk.org/ under Metadisk. As for DriveMiner, drive farming demonstration will be out in the next couple of days. Perhaps by the next community chat. I just got back from the Chicago conference, and will me on by way to Coin Congress tomorrow, so I haven't had too much sit down development time.
If any of you are going to be at Coin Congress let me know.
