DX10 for Windows XP?

Hey, I just heard about some software made by Falling Leaf Systems, they call it "Alky for Games". If I understood this right, they are essentially attempting to make Vista-only games, such as Halo 2, or DX10 games (not entirely sure which) work on Windows XP. Currently they have a pre-alpha build that you can download. Has anyone tried it?

If anyone does dare to try it, please let us know if it worked

Last time i looked a few months back it wasn't a working solution anyway. They had only got so far as being able to use a few functions of DX10. Maybe in a year or so they might have something that works. But by then most will has gone over to vista anyway or completly givern up on microsoft.

DX9 is on XP.

Halo 2 is a DX9 game, but it will look for DX10 extensions (M$ way of forcing people to upgrade to Vista) to install or play. Now if M$ improved the game to include some actual usage of DX10, then I suppose it will make swallowing Vista (and DX10) a bit easier.
