I've seen a couple of "short lists" posted - are you guys aware of http://uservoice.com/ ? Here is a live site if you want to poke around: http://paraview.uservoice.com/
It is a really nice way to (openly) keep a list like this and collect in an extremely organized fashion users wants and needs. And unless they changed it, it is free if you get less than 100 comments or something like that per month (if you get more than that, it would probably be worth paying for!)
Just a thought!
