> As far as I can tell, there is no way to track the actual bytes downloaded except for changing network stacks to something like ASI's. 
> Lame other option #1:
> Re-gzip the response locally to approximate.
> Lame other option #2:
> Send a second request HEAD request without accept-encoding header (while the first request is in progress), and that will tell us the expected non-compressed length. This option is actually reasonable I think.
