Using the same positional parameter for two things (argv[3] can be either de verbose mode or a host) is not very smart... but I think that is the easiest way of doing. 

We definitively need to improve the argument passing in Python, to use the same style than CB, e.g. `./accumulator-server.py -port 1028 -url /accumulate -host 10.1.1.1 -verbose on`). There are libraries to do that, but I need to check them out.

@rbl219 , could you please open an issue with priority P4 and assign it to me?
