Argyll now integrates with the 0.7 beta version a way to support the Spyder2 from Colorvision. This is not a direct support though, as Argyll still needs to use the "genuine" binary compiled version delivered with any Spyder2 device. Through a dedicated Spyder2 module, Argyll will ask you to give him a path (CD or whatever) to the Colorvision/Spyder2 installation package. After that, you can perform a "regular" profiling of your monitor using the dedicated Argyll module.

I still have to explore this software and provide here some figures at how well it performs against a profile produced by the Colorvision software under the Windows OS.
