I don't have 64-bit Windows installed, but I can get it from MSDN. That would take me quite while to get everything up and running.

Also, I can't seem to download the source code from the CVS for qliner for some reason. It keeps saying the repository has been relocated temporarily. However, I took a browse through the online version of the code and it appears to be straightforward C# for the most part coupled with a Win32 C++ hook. Also, the C# .csproj files show that the executables weren't compiled to be 32-bit specific so it is highly like that qliner is having the same problem that Circle Dock has and you simple just have to add in the instruction to build as x86 into the .csproj files.

- hide the dock when you click out of the circle.
This should be doable but it may be a little difficult for me to do it right now with the state of the code.

- add the possibility to not show the dock when it is launch. I launch it at Windows's start and it's not necessary to show it.
This is doable. I'll add in an option for it.

- add differents actions for the central button (launch a program for example).
This is doable and I will incoporate it for the next major release.

- hide the icon in the systay
This is a possibility. I just have to make it so that either the settings panel or the dock itself shows up if you try starting the program again. I was just afraid that some people might hide their dock and not know how to call it back up.

- add the possiblity to make a shortcut with shift, control or/and alt AND a mouse button (for example, Shift + Right Click) to show the dock.
Edit : I just noticed sometime the dock doesn't get the focus when it is shown, so we can't use the wheel to turn it.
I was just doing some development on Circle Dock yesterday and for Video In Picture and I will be adding in more mouse combinations to toggle Circle Dock with in the next major release. I have fixed the X1/X2 mouse button distinction, added in the ability to use left-right mouse click combo to toggle the dock, and I will added in the shift+click, ctrl+click options. As a result of the changes I've made to the toggling code, I also believed I have solved the issue of the dock not getting focus sometimes when you use the mouse buttons to toggle it. Essentially, the Orbit.Hook.dll code that was responsible for calling the dock up when you used a mouse button was using PostMessage(...) instead of SendMessage(...). The former command doesn't wait for the dock to execute it's code while the latter does.

I was one of those in the closed betas and got to try Camspace out. It does work like what you see in the videos and is well implemented but you really need to have lots of lighting in the room and the object you choose should not be similar to the colors in your background or the program can track off course. I still don't think it's a threat for conventional gaming or the Wii because it's pretty hard to use it to replace hardware controllers, especially if you want to push a button or you have lots of intricate commands for the game. I've seen people try to use it to replace a mouse but it doesn't work very well because you can't emulate all the buttons and mouse movements easily and naturally. Perhaps if you build an operating system around Camspace it would work out better.
