the way you've coded your server, the client should call myserver.add(2,2)
and NOT what you've coded on the client side.

To see why add a simple print of method and params as the first line
of _dispatch and you'll see:

for the call to .add(2,2):
dispatching 'add' (2, 2)

for the call to ._dispatch('add', [2,2]):
dispatching '_dispatch' ('add', [2, 2])

i.e. the way you call it string '_dispatch' becomes the method and the tuple
of args that ends in params isn't what you apparently think it should be.
