nginx currently can limit bandwidth only on per-connection basis.

But we can limit rate for each connection, and than limit maximum number of connection to each 
virtual host.

Somethings like:

http {
   limit_rate 250000;
   limit_zone conn_to_server $server_name 10m;

   limit_conn conn_to_server 100;

   server { ... }
   server { ... }
   server { ... }
}

With this settings each virtualhost can't use more than  250000*100 = 25 Mbit of bandwidth.
