Presumably if an upload tracker is required, the number of requests 
relative to the volume of data transfer will be low (at least for this 
type of operation on that server), so even if the other server isn't as 
perfomant as Nginx, I don't think this should be a problem.

Robert could of course install Nginx on the other server as well, or 
perhaps even just make a call to a FastCGI/WSGI process directly from 
Nginx.  :-)
