I have had a quick look at the module and I don't think that there is anything wrong with it - if you have been using it succesfully up till I wouldn't let the 'Alpha' tag put you off too much, module authors will tend to label modules as alpha not so much as a comment on the code but rather to indicate that it is still being actively developed and that the interface and or implementation may change from release to release and even so most authors will, on a radical overhaul of the modules interface, will leave some backward compatibility path for existing users.
