I think so :-) unless some socket code is looking at the actual class of
the socket.
But why not just override socket.accept() to do what you want? Here is
the full def of socket.accept():
def accept(self):
sock, addr = self._sock.accept()
return _socketobject(_sock=sock), addr
Just change it to
def accept(self):
sock, addr = self._sock.accept()
return MySocket(_sock=sock), addr

Google "site:docs.python.org __class__" and especially
http://docs.python.org/dev/lib/specialattrs.html
