i could see for OOo the need and maybe firefox  but that is really about it.  
X in the old days  but no now.  If the user is not really wanting to update 
because of to many updates chances are that they dont have the latest 
versions installed.  Im not saying that we should not do it.  Just that 
personally im not a fan,  and I dont think the gains will be worth the pain.  

Please prove me wrong if i am.
