 (on-line) upload to HTTP interface) so that the gateway doesn't use the
 disk at all. #320 would offer great improvements, IMO, in performance and

 When you do a byte-range GET request, you lose streaming downloads.

 Oh, right, *downloads* when you are doing a range-request. My favorite
 solution to that is #798 (improve random-access download to
 retrieve/decrypt less data) so that the web gateway downloads only the
 segments needed to satisfy your range request and just keeps them in RAM
 until it has satsified you.
