Wouldn't that open up a can of worms in terms of security of the 
application? If setting an environment variable is enough to change what 
libs get loaded and you can point to arbitrary different libs, that 
means injecting your own code in other peoples applications becomes 
really easy, right? I think you could use that to get rights escalation.
