I think pricing per MB/GB makes more sense, but hey you could have it both ways, or impose caps, all priced up and selectable in-wallet.

Prices in that poll are on the high side IMO...  

(10 cents / 0.0275 DRK (current exchange) * 1000000 daily users) / 1000 MNs = still 27.5DRK or ~$100 per day.

There is absolutely going to have to be a minumum MN spec (bandwidth!) for this though. And it's going to be near impossible to enforce that, so some mechanism for booting shitty underspecced VPS's off the network would need to exist.
