I'm not sure it's possible to make complete workarounds. In the idealized  
case, Linux depends on the execute being set.  Many desktop users will  
have wine installed, though, in which case the wine program loader will  
pick up and execute the file, regardless of any extension.

(It can of course be argued that this is a fundamental problem of how wine  
is set up to integrate with the OS)
