I did not want to spend money on ARD so I've used Chicken of the VNC and it can't be compared to Apple Remote Desk Top .
The only good advise I can give you, it's to buy a ARD for 299 $ / €
This is giant leap forward, it work like magic !
You don't only perfectly remote your HUD , you can even throw away you local monitor , and goes directly from GUI to Display/Projector .
Think of the cost of all that useless hardware inside the Box , 2 vga Splitters two monitors cables and all that cost at least 1000 euro per server ! With Apple Remote Desktop you've done the same thing spending 299 per 10 servers .
it might sound extreme but this is the way I'm doing .
