At least Storm would not be able to function and you would definitely know it was there (it attempts to use port 25/SMTP).  However, the person who blogged the article was not able to get a keylogger to run successfully.  I consider that an improvement as a normal user running Wine should not be able to grab the keyboard.  It will be interesting to see if this will be possible as improvements are made to Wine.
