1. BAM! Fixed, thanks for the catch :) 2. We have to download the files anyway, there's no go-between or else we wouldn't have had to build one! 3. We throttle monster files down and are currently building out our distributed infrastructure.

What I meant by #3 was you only have a finite amount of relatively pricey space on your DropBox account(s).

That's something we're well aware of. Current average usage doesn't indicate it'll be a big problem. Otherwise, it's a good problem to have :)
