 This has a small risk of displaying some traces a little out of sync, since
 it will do batch sorts of input events. Similarly, you can do traces over

-% blktrace -d /dev/sda -o - | netcat parsehost portno
-% netcat -l -p portno tracehost | blkparse -i -
+% blktrace -l

+% blktrace -d /dev/sda -h <server hostname>

+to connect and transfer data over the network.
 
-Which will send the traces from tracehost to parsehost over the network on
-the defined port number.
