I think Gaiafile and uploadstation has that kind of potential.
imho uploadstation is going to do it
@cloud, BitShare ain't good at all. They are notorious for deleting files even without DMCA notices, probably to clear HDD space. I don't think they have enough servers to keep up with the demand. They also don't offer unlimited space for premium users which is another indication of the same.
I think Duckload is the closest to FS and FSC at the moment. They are going quite steady for a while now. Dunno about Gaiafile but Uploadstation looks decent but too early to judge these hosts.
