Hey again Steven,
  I'm still having problems...

The problem is:
>>> c.func_b.__name__
'wrapper'

That messes up SOAPpy's RegisterFunction() method which apparently depends
on the __name__ of the function to publish it as an available SOAP
function.

Any suggestions on how to change the name of c.func_b to 'func_b' instead of
'wrapper'?
