Linux?

[RedSoxFan04]

Can this be used on Linux? Perhaps through Mono?

It requires the microsoft COM library and the microsoft ATL template (which is a "simple" way to use COM in c++), so I don't think this could run on Linux any time soon.
To be honest, I'd feel lucky just to get this working on windows.

Their SDK just communicates with the MysticLight service which does the hardware communication (that's why the DLL doesn't do anything unless the software is installed as well). So being able to use their DLL won't do any good - you'd have to reverse engineer their service instead and figure out how it communicates with the hardware.
